N2O is easily available and should be in your toolkit...

[hell toupee]

The more I look in to it, and believe me, I've done some due diligence, as the user @Intoxicated says and who originally pointed me in this direction, I absolutely agree with him. If Nembutal was the gold standard for MAID laws and right to die like Exit Intl, etc., then Nitrous Oxide should be the platinum standard.

For one, even if it's not used as a method, it basically erases SI and takes the edge off. Believe it or not, ironically, N2O is being studied right now because it has been shown to attenuate suicidal thoughts. It's an anxiolytic and reduces anxiety as well. I'm not talking about taking it all the time. I'm simply referring to taking a few hits right before I commit to my primary method.

N2O is not my primary method, however it is my backup method, and to be honest, after studying N2O for a few months, it may take the top spot. It's easily attainable from Amazon. There is ZERO discomfort.

I'm going to make a prediction right now. Sooner or later, N2O is going to catch on, and just like SN or Helium, it's going to eventually get banned because too many people are using it to ctb.

@Intoxicated just wanted to share, I had bought a 2 pack of the 3.3L cylinders, which came in a regular nondescript box. The problem, as you know, is, you need a special regulator to use it and a lot of them on Amazon seem to be low quality control - they are hit or miss, sometimes people get one that works great, others get ones that leak and make the cylinder useless.

I found this little mini pressure regulator last night, that has some good reviews because it's so simple. It cracks the 3,3L (and other) cylinder, and just has a button you push (release valve - red) that comes out the top of the gas outlet. It's half the price of the other regulators, and very simple. You can put a balloon on the gas outlet and fill it that way, or, you can connect a 1/4" ID silicone tubing to fill a medium sized trash bag (13 gallon in US is what I'm using - about the same size as 65cm x 65cm I believe).

I'm not using continuous flow - you can't do that with this. But it would be perfect to just fill a bag for a simple, closed system, where little can go wrong.

Hm, very interesting post and looks promising. I did look up N2O on Amazon, but I could only find whipped cream chargers, and I'm not sure if that's the correct thing to buy or if they will even work with the regulator. And it looked like they were mostly $50 - $100... I mean ig not a horrible price to pay for a peaceful death, but still. Not super cheap.

Yes, they have the cartridges, which require a cracker ($10-$15) and balloons, and you could do it that way, it's just a little more complicated to transfer the N2O from the balloon to a plastic bag.

However, you can get the cylinders. They are smaller than like a helium or Nitrogen cylinder, about the size of a small fire extinguisher - a little smaller than a 2 liter soda bottle (skinnier). But used with just a simple regulator like above, for about $100, you could have a very peaceful ctb. Just as peaceful, if not more so, than Nembutal. That's worth it if you ask me. Obviously a tad more complicated than swallowing 10g of N, but if you really think about it, CTB is a very big and final decision. Making a little effort to insure a peaceful and guaranteed ctb is worth it to me. If it;s too easy, it prevents an impulsive, possibly reckless decision that could be a huge, irreversible mistake. CTB is no joke, and should be the absolute last resort for anyone. Not an easy, quickly made decision, imo.

For one, even if it's not used as a method, it basically erases SI and takes the edge off. Believe it or not, ironically, N2O is being studied right now because it has been shown to attenuate suicidal thoughts. It's an anxiolytic and reduces anxiety as well.

I'd say that it's very likely that the anxiolytic effect wouldn't be achieved until approximately 1 minute or more is passed after inhalation of the gas has started. The peculiar symptoms of and LOC from asphyxiation may take place faster than any N₂O-specific effects (which make it notably different from other simple asphyxiants like nitrogen). And those symptoms can make you anxious.

People who have tried small doses of pentobarbital told that they felt very sleepy, so OD on this substance would likely feel just like falling asleep. Gas asphyxiation is entirely different in this regard. It doesn't cause that specific feeling like you want to sleep. Instead, you experience gradual transition to unconsciousness, possibly with hearing noises (I heard high pitched ringing together with a sound that reminds wind from fans), numbness, some fullness of head, acceleration of heartbeat, the urge to breathe more quickly and deeply (alkalosis caused by hyperventilation performed beforehand seems to be able to suppress this urge), loss of the sense of gravity. Although these sensations didn't cause physical discomfort in my case, they seemed really weird and unnatural. You can have an impression like you're dying.

If you try N₂O, I'd highly appreciate your feedback. It would be interesting to compare your perceptions and impression with mine.

I'll reply a little later, but yes, I've tried it.

I had ordered 3.3l canisters, which I was saving for my ctb (either tonight or tomorrow morning) and also ordered cartridges, cracker, and balloon to test with.

2nd test I didn't get a full balloon, because I didn't realize you have to tighten cracker and then back off (unscrew) a tiny bit to let gas out - I originally just kept tightening and nothing was coming out.

I became disabled in my hands little over a year ago, part of reason I want to ctb.

First test I took 3 deep hits and passed out while laying down.

2nd time (last night), because I have to use pliers, I only got little less than half balloon.

You are right, no sleepy feeling like opioids/barbiturates. Just light headed, euphoric feeling (not scary at all, very pleasant). 1st time was fast - loc maybe about 30 seconds.

2nd time, small hit, I received light headed and euphoric feeling, just not as strong. Did not loc obviously.

Both times, I did not maximal exhale beforehand, nor did I hyperventilate. I Just held in the N2O, not long as possible, but maybe hold in N20 about 15-20 seconds, like a Marijuana hit. I could've held in longer, but was satisfied that loc is pretty reliable, especially if combined in closed environment like small bag.

I won't have issues with my hands and crackers when I use 3.3l cylinder and mini regulator to ctb - its just a push button and I can use my thumbs fine, no screwing or unscrewing of cracker.

Loc test, I was surprised how fast it happened. I just felt light headed, little bit ringing in ears, and my vision quickly narrowed. Then I passed out. Was surprising how quick this happened but it was definitely noticeable that loc was coming on.

Did you have same experience? How many inhale breaths did you take? In 1 video you posted, it show 1 guy inhale 1 balloon 3 times, then he stumbled forward and fell on his face in to a couch (loc). I couldn't see - did he take 1 breath, exhale, then take another and another? Or 1 breath, pause, another inhale, pause, and then 3rd inhale without exhaling in between each inhale?

 

[Intoxicated]

I just felt light headed, little bit ringing in ears, and my vision quickly narrowed. Then I passed out.

You don't recall numbness and tingling?

Did you have same experience?

I have somewhat poor memory, so my recollections may be inaccurate. Here is an approximate order of appearance of the symptoms as I remember it at this moment:

Stage 0:
No symptoms.

Stage 1:
Clouding of consciousness, the sense of impending fainting.
Tinnitus (high-pitched ringing in the ears).

Stage 2:
Blurriness and dimness of vision.

Stage 3:
Weakness, loss of coordination.
Double tinnitus (high-pitched ringing & wind-like noise).
Desire to resume breathing (if the breath is held) or breathe faster and deeper.

Stage 4:
Numbness in the face and lips.
The sense of slight tension in the head.
Tinnitus becomes weaker.

Stage 5:
Profound numbness in the whole body, loss of the sense of gravity.
Tingling sensations in the face and lips, palms and fingers of both hands.
The feeling that unconsciousness is very close.

Stage 6:
Loss of consciousness.

As for euphoria, I never had it appearing before LOC or near-blackout stages. On a few occasions, I had it after about half a minute during moderate hypoxemia that didn't cause the sense of numbness. Whenever the stage of hypoxic numbness was reached, the euphoric feelings appeared only after full recovery of consciousness or didn't appear at all.

In some cases, after full consciousness returned, I noticed slight numbness in the arms that lasted for a few minutes, this was likely caused by the anesthetic properties N₂O.

How many inhale breaths did you take?

Either one very deep breath or multiple breaths in the experiment with inhaling from a plastic bag (I was counting seconds instead of breaths, so can't tell how many breaths I made). It's worth noting that I couldn't pass out from a single deep breath of nitrous last time, even though I held my breath for about 45 seconds. I was very close to blackout, but didn't lose consciousness completely.

In 1 video you posted, it show 1 guy inhale 1 balloon 3 times, then he stumbled forward and fell on his face in to a couch (loc). I couldn't see - did he take 1 breath, exhale, then take another and another? Or 1 breath, pause, another inhale, pause, and then 3rd inhale without exhaling in between each inhale?

You mean this one?

He did at least 6 - 7 inhalations (the first one is not visible, but we can hear it). His breaths were relatively shallow, and I think that he could have passed out faster if he breathed deeper.

How long does the average loss of consciousness last for, before you start waking up from it and becoming aware of reality again?

And what method do you plan to combine N20 with?

 

[hell toupee]

How long does the average loss of consciousness last for, before you start waking up from it and becoming aware of reality again?

And what method do you plan to combine N20 with?

First question, it depends. Are you talking about inhaling off of a balloon, holding in the N2O, and then just resuming breathing normal ambient air (like most people who do it recreationally)? You wake up pretty quickly - in my experience once O2 is re-introduced, you are awake within 3o seconds.

However, @Intoxicated knows a lot more about N2O than I do, so he can probably give you averages.

For your second question, are you speaking about my primary method? It's a cuff device similar to the KRA Cuff, which can be found on Google.

That said, I'm going back and forth whether or not I might just use N2O as my primary and only method. People who fill plastic bags with N2O and start breathing that in pass out quickly and comfortably, and just don't wake up. And no, a reflexive response like hypercapnia is not possible in a brain without enough oxygen to sustain consciousness. Furthermore, Intoxicated, correct me if I'm wrong, I believe N2O has been shown to attenuate the hypercapnic response, even if there was one.

@Intoxicated - I will answer your questions after dinner.

 

[homeboundcripple]

Thanks for the heads up, should imagine this would pair very well with CO, a nice euphoric feeling right before passing out.

I did not notice much tingling, no. Perhaps a little bit, however I should qualify my perspective.

I have extensive nerve damage in my extremities (fingers & toes) and basically live with constant tingling, or pins and needles sensations every waking moment.

So it could be I'm a little desensitized to those sensations, or it could be possible that this aforementioned neuropathy interferes with me feeling the same thing a healthy person would.

Do you experience these sensations in your extremities?

As to the stages, to be honest, it happened so fast, and with not really knowing what to expect, I obviously was not as observant as you were.

As you mention some of the effects, they do start to ring a bell. The slight numbness in the lips was felt.

Not so much tinnitus. But yet again, that could be a me problem - before becoming disabled, I used to play drums and was in a few bands. Although my hearing still seems to be normal, I do have a low lying, kind of persistent ringing in my ears. Not usually noticeable unless I pay attention to it, but it's there.

I did not necessarily feel any profound numbness of my entire body, nor notice any effects with gravitational force, however I was laying down.

Unfortunately, as I said, it just seemed to happen really quickly, and with my physical problems, I probably don't make a good trip report.

As to euphoria, it was very subtle. Thinking about it, my sensation could very well be more of a product of being a little anxious beforehand, then realizing I was worried for nothing and actually quite relaxed, then reporting that return to baseline as "euphoria".

To be clear, it was most certain nothing even approaching something like the rush, or euphoria felt with opioids/opiates. I am an experienced (and now sober) functioning opioid addict, so I am well aware of what proper euphoria feels like - if I wasn't, I wouldn't of thrown away all of those years wasting my time and money on such.

If you could call this euphoria, it was extremely subtle. Maybe a better word is relaxed. Actually, an even better descriptor would be "content". Considering what is at stake, I felt content.

Honestly, why even bother with CO?

Unfortunately its heavily regulated here in the UK, hopefully I'm able to get my hands on a couple of small canisters and just use it as an aid to mask CO symptoms.

 

[diagon24]

Could this be paired with jumping? Ie you take a few breaths of a balloon whilst on the edge leaning slightly then fall unconscious to get over the SI of going over?

There is other possible explanation: hypoxia can alter your ability to memorize the events precisely. For example, take a look at this

At the end, he couldn't remember what he said, although he wasn't even close to passing out. At the stage when tingling sensations appear, you'd be barely able to talk.

Do you experience these sensations in your extremities?

I can recall them when passing out was relatively slow, but not when it was fast.

As to the stages, to be honest, it happened so fast, and with not really knowing what to expect, I obviously was not as observant as you were.

I totally understand. It may be difficult to focus on your perceptions, catch them all, and remember them clearly when you deal with multiple different divergences in relation to your normal senses and they appear for just a few seconds while you're in an altered state of consciousness.

I did not necessarily feel any profound numbness of my entire body, nor notice any effects with gravitational force, however I was laying down.

I was lying on a bed too. The period when you could experience those perceptions is very short, and it comes promptly before loss of consciousness, so it's very possible that you couldn't notice or memorize such events.

As to euphoria, it was very subtle. Thinking about it, my sensation could very well be more of a product of being a little anxious beforehand, then realizing I was worried for nothing and actually quite relaxed, then reporting that return to baseline as "euphoria".

If you could call this euphoria, it was extremely subtle. Maybe a better word is relaxed. Actually, an even better descriptor would be "content". Considering what is at stake, I felt content.

The first time I was anxious too, then, after consciousness was fully regained, there was a feeling of relief that nothing bad happened, then I wanted to laugh and I was laughing for about a minute, and after that I felt content as you said.

First question, it depends. Are you talking about inhaling off of a balloon, holding in the N2O, and then just resuming breathing normal ambient air (like most people who do it recreationally)? You wake up pretty quickly

That's right, people tend to regain consciousness in a few seconds. And this is good for testing, because this means that we can induce hypoxia briefly, with minimum harm to health and minimum risks. This makes testing the effects from asphyxiation by N₂O notably different from testing poisoning by CO or SN as, for example, in this recent story

SN-Ingestion Report: My Terrifying Brush with SN-Fueled Hypoxia Hell

My SN ingestion report and its risks and effects This report is based on my personal account of ingesting a small dose (3.1 grams) of SN out of curiosity, not as a suicide attempt. This report is to highlight the severe risks, unpredictable effects, and potential consequences of reckless...

sanctioned-suicide.net

Some symptoms mentioned there sound pretty familiar to me - ringing in the ears, blurriness of vision, numbness, tingling. But with N₂O I had them just for a few seconds, not minutes, and there were no any remarkable sequelae. No headaches, no fatigue, no problems with concentration, no problems with stomach. The recovery is quick and flawless.

Could this be paired with jumping? Ie you take a few breaths of a balloon whilst on the edge leaning slightly then fall unconscious to get over the SI of going over?

That wouldn't be jumping, just falling. And your falling would likely begin before consciousness is fully lost, because you lose the ability to control your muscles a few seconds before unconsciousness sets in.

 

[hell toupee]

There is other possible explanation: hypoxia can alter your ability to memorize the events precisely. F

Yes, I have read this in the literature.

I had also read that occasionally people will mimick movements they were making just prior to N2O ingestion. For example, if someone is scratching their head just before inhaling N2O, they sometimes were observed going through the same motions without any conscious awareness of such. Not common, but it was noted.

Do you think this only occurs during later stages of exposure? This was with N2O/O2 mixtures, like what is used in a dental setting - could that have anything to do with it?

My concern is not that I might reverse my protocol subconsciously while waiting for LOC, more that there might be a possibility that I unknowingly start fiddling with the setup, or seal around the neck. I plan to use a rubber band and plastic wrap, since it's strong and flexible if wrapped around several times. It also doesn't require the finesse that something like tape would. I live 1 block from the Pacific Ocean, so I live in a very moist and damp environment. With that, and any body sweat, no matter how little, I'm dont like there a possibility where this could disrupt the adhesive on the tape.

Do you think this movement phenomena is something that probably happens after LOC in our context?

totally understand. It may be difficult to focus on your perceptions, catch them all, and remember them clearly when you deal with multiple different divergences in relation to your normal senses and they appear for just a few seconds while you're in an altered state of consciousness.

Agree. The first time you don't really know what to expect, and I wasn't necessarily thinking about paying attention to the stages of effects.

However, it seems as though there are absolutely no unpleasant side effects or issues to deal with when testing or inhaling N2O, so I could see where a 2nd test with a little more attention paid to the subtle nuances could be relatively simple to conduct.

Some symptoms mentioned there sound pretty familiar to me - ringing in the ears, blurriness of vision, numbness, tingling. But with N₂O I had them just for a few seconds, not minutes, and there were no any remarkable sequelae. No headaches, no fatigue, no problems with concentration, no problems with stomach. The recovery is quick and flawless.

Agree 100%. I dare say, I think it's better than Nembutal or Seconal. With both, vomiting and nausea is a real concern. Plus, just because you ingest 10g does not guarantee ctb.

However, with N2O done properly, and it's fairly simple to do - much easier than CO or inert gas as there are a lot of variables that could make those methods fail, it seems to me that nobody can escape hypoxia.

That said, I came to something of an epiphany last night. I fully confess that I'm a worry wart, which causes me to obsess over any detail or variable that might potentially cause me to fail.

I have spent a lot of time, research, discussion, and careful consideration towards my decision to ctb and the method I will use. I have never made an attempt because I will only make 1 attempt. I cannot entertain any possibility of failure - zero.

Originally, I was going to have a primary method, which is just night night method but using inflatable air shims/wedges instead of corn hole bags or knotted up socks at the carotids. Since there are 2 inflatable shims, 1 goes on each side of the neck. Unlike night night, or ligature, or hanging, I am not putting pressure around the entire neck, because pressure on airway is not fun. I am only pressuring the sides. I had planned to slip a plastic bag over my head just before inflating the shims, for insurance.

My backup method was N2O - if anything went wrong with the cuff device, which I've spent 6 months developing and working out every variable to human anatomy so there is very little that could go wrong, I worry, and needed 3 backups. If N2O failed, the last resort was fs hanging.

It hit me last night that if I combine the night night kra cuff style device with N2O, I think this basically gives me near 100% probability that not only is LOC quick, but ctb is guaranteed in less than 20min.

With the cuff occluding up to 80% of the brain's oxygen and glucose supply, the little bit of blood still flowing to the brain through the vertebral arteries/etc., would have such little oxygen that this would be an incredibly drastic reduction in the brain's oxygen supply. I would literally just combine both methods, with a small trash bag of N2O secured over my head. I hold my breath after it's filled, seal with plastic wrap, and the shims have little squeeze bulb pumps that hang down in front of my chest. I give those a few squeezes, which inflates the shims and pushes in on my carotids. I then take a deep inhale of N2O and pass out, most likely in <20 seconds.

Basically, I don't need anything near full 80% occlusion with the cuff device, since the blood will be oxygen starved due to breathing N2O in a sealed plastic bag.

This would also not require the N2O concentration to be as strict in the bag.

If you still have some N2O, take a hit or 2 from a balloon and then pinch your neck (carotids) with your fingers or the heels of your palms. Even if you can't normally get yourself to pass out by pinching the carotids on their own, if you do it with a hit of N2O in your lungs, you will most likely loc in less than 5 seconds. Or, this is my anecdotal experience.

It works with hyperventilation as well. You don't even need to hyperventilate for very long. If I HV for 30 seconds, I don't pass out. If I just pinch my carotids, it's also difficult and usually requires adjustments and trial and error. However, if I HV for 30 seconds, and pinch anywhere close to my carotids, Im almost instantly out. Like in 2-3 seconds.

There would be no possibility of coming back from the compounded effect of that much o2 deprivation. Either method alone, as you know, is reliably lethal.

I realize you like things simplified, so this definitely is just a method tailored for me and my neverending worry habit. It gives me the peace that once I commit, I have something fast, peaceful, and reliable.

One question though. In one of your past posts, you mention squeezing the top of the bag to empty approx 1/4 to 1/3 of the gas volume in the bag before sealing around neck. What was your purpose for this? To prevent overpressurizing the bag once it's sealed? Maybe to purge any possible ambient air that entered when pulling the bag over the head? Why not just fill the empty bag while it's around your forehead so you eliminate leakage when trying to get it over your head?

The more I look in to it, and believe me, I've done some due diligence, as the user @Intoxicated says and who originally pointed me in this direction, I absolutely agree with him. If Nembutal was the gold standard for MAID laws and right to die like Exit Intl, etc., then Nitrous Oxide should be the platinum standard.

For one, even if it's not used as a method, it basically erases SI and takes the edge off. Believe it or not, ironically, N2O is being studied right now because it has been shown to attenuate suicidal thoughts. It's an anxiolytic and reduces anxiety as well. I'm not talking about taking it all the time. I'm simply referring to taking a few hits right before I commit to my primary method.

N2O is not my primary method, however it is my backup method, and to be honest, after studying N2O for a few months, it may take the top spot. It's easily attainable from Amazon. There is ZERO discomfort.

I'm going to make a prediction right now. Sooner or later, N2O is going to catch on, and just like SN or Helium, it's going to eventually get banned because too many people are using it to ctb.

@Intoxicated just wanted to share, I had bought a 2 pack of the 3.3L cylinders, which came in a regular nondescript box. The problem, as you know, is, you need a special regulator to use it and a lot of them on Amazon seem to be low quality control - they are hit or miss, sometimes people get one that works great, others get ones that leak and make the cylinder useless.

I found this little mini pressure regulator last night, that has some good reviews because it's so simple. It cracks the 3,3L (and other) cylinder, and just has a button you push (release valve - red) that comes out the top of the gas outlet. It's half the price of the other regulators, and very simple. You can put a balloon on the gas outlet and fill it that way, or, you can connect a 1/4" ID silicone tubing to fill a medium sized trash bag (13 gallon in US is what I'm using - about the same size as 65cm x 65cm I believe).

I'm not using continuous flow - you can't do that with this. But it would be perfect to just fill a bag for a simple, closed system, where little can go wrong.

Amazon

Unfortunately any canisters, including N2O, can't be delivered to Amazon lockers because they're considered hazardous. Just an FYI for anyone who doesn't live alone and may have to worry about someone else opening their packages.

 

[Intoxicated]

I had also read that occasionally people will mimick movements they were making just prior to N2O ingestion. For example, if someone is scratching their head just before inhaling N2O, they sometimes were observed going through the same motions without any conscious awareness of such. Not common, but it was noted.

Do you think this only occurs during later stages of exposure? This was with N2O/O2 mixtures, like what is used in a dental setting - could that have anything to do with it?

That sounds like the behavior described in clause (1) here

CHAPTER VII. EXCEPTIONAL CASES.

Muscular phenomena during inhalation.

These may comprise

(1) Strictly voluntary movements at the outset of the administration, as, for example, putting up the hands with the object of removing the face-piece, etc. Some patients imagine that by moving their fingers, hands, or feet, at the beginning of the administration, they may afford valuable assistance to the anaesthetist by providing him with a reliable sign that consciousness is present. Unfortunately, movements originally voluntary not only tend to become automatic as consciousness becomes lost, but they may even increase to such a degree that the patient's whole body shares in the movement.

(2) Uncontrollable nervous movements, also at the outset of the administration, e.g., tremor of the legs, or fidgety movements of arms, hands and fingers.

(3) Intoxication-movements, such as movement of the head from side to side, stamping, alternate thrusting out of the arms, etc. Such movements as these are often associated with laughter or shouting, and like the latter are due to air or to too large a percentage of oxygen in the mixture.

(4) Tonic spasm. Some degree of tonic spasm is not uncommon, especially in men, but extreme conditions, such as those to which the terms opisthotonus and emprosthotonus have been applied are very rare. Sometimes the tonic spasm affects the neck muscles, and the head gradually becomes turned to one or other side. It is difficult to say what these movements depend upon. In many cases they occur when the percentage of oxygen is rather less than usual, but this is not always so. Indeed, if the patient be a vigorous, athletic man, and too much oxygen be admitted with the nitrous oxide, excitement will arise, and marked rigidity may be occasioned. It is on such occasions as these that some degree of respiratory spasm, from contraction of thoracic and abdominal muscles, is prone to occur. In this way a primary excess of oxygen may lead to secondary cyanosis, or even to jactitation.

(5) Clonic spasm. Epileptiform twitchings always indicate a diminution in the normal oxygen supply. When the diminution is but slight the clonus may be so mild that it may escape detection. The most marked clonic spasm (jactitation) is met with in children when nitrous oxide free from oxygen is rapidly inhaled. The epileptiform movements may affect all parts of the body. Whenever the anaesthetist detects any such movements commencing during the use of nitrous oxide and oxygen, he should at once increase the oxygen supply, and the movements will quickly vanish.

(6) Fine tremor of arms and legs occurring during unconsciousness. This is rare; I have only seen it in three or four cases, and it came on when anaesthesia was fairly well established.

(7) Certain peculiar tonic movements of deep anaesthesia. These are very remarkable. After a long inhalation of the gases, and when anaesthesia is well established, as may be seen from the state of the eyes, patients sometimes display peculiar movements of the arms, legs, neck, and body. The arms and legs will slowly move in a certain direction; the head will slowly turn to one side; or the whole body may begin to turn gradually in one direction or another. The movements often suggest a return of consciousness; but this is not so. When the face-piece is removed, a long and perfectly tranquil anaesthesia follows. The tonic movements differ from those referred to in (4), for they come on after relaxation of the muscular system has been produced. For want of a better term I have called the condition "secondary rigidity."

Do you think this movement phenomena is something that probably happens after LOC in our context?

I'm skeptical about a possibility of coordinated movements in unconscious state. The person may seem unresponsive to an observer and not remember about doing something, so some people could presume that consciousness has been lost at that moment, but these two conditions do not actually exclude a possibility of limited consciousness with amnesia.

My concern is not that I might reverse my protocol subconsciously while waiting for LOC, more that there might be a possibility that I unknowingly start fiddling with the setup, or seal around the neck.

If you worry about such things, you could consider handcuffing.

The first time you don't really know what to expect, and I wasn't necessarily thinking about paying attention to the stages of effects.

Those stages are somewhat artificial. It was apparent that various symptoms appeared at different moments, so I decided to divide them into groups, which I called "stages", in order of their appearance. Symptoms grouped together in a particular "stage" appeared simultaneously.

I dare say, I think it's better than Nembutal or Seconal. With both, vomiting and nausea is a real concern. Plus, just because you ingest 10g does not guarantee ctb.

In the context of test-ingesting, pentobarbital may be not that bad. Some users of this forum ingested it in therapeutic doses in order to figure out how it works as sleeping aid. This may not give the full picture of ingesting a lethal dose though. By the way, nausea is a possible (but not very common) after-effect of nitrous oxide administration.

However, with N2O done properly, and it's fairly simple to do - much easier than CO or inert gas as there are a lot of variables that could make those methods fail, it seems to me that nobody can escape hypoxia.

I don't see significant advantages of N₂O over inert gases in terms of simplicity and reliability. CO poisoning would likely be more reliable than both when the gas is produced via a laboratory method (f.e., through decomposition of citric acid by concentrated sulfuric acid) and administered in an optimal way, but the process of making CO requires way more effort than just releasing N₂O from factory-made chargers.

One question though. In one of your past posts, you mention squeezing the top of the bag to empty approx 1/4 to 1/3 of the gas volume in the bag before sealing around neck. What was your purpose for this? To prevent overpressurizing the bag once it's sealed?

Initially the gas is relatively cold. When you breathe it in and out, it becomes warmer and undergoes thermal expansion. Although some mass of N₂O will be dissolved in blood plasma, thus reducing the remaining mass of the gaseous mixture in the lungs and the bag, I have no quantitative estimations of how much this dissolution would negate the potential increase in volume due to thermal expansion, so it could be useful to remove some volume of the gas as a safety measure against excessive pressure in case if the bag seems fully inflated or nearly such right after it's placed over the head. But it's very possible that a significant volume of the gas will escape during the process of placing the bag over the head, leaving enough room for further expansion without any special effort.

Maybe to purge any possible ambient air that entered when pulling the bag over the head?

It may be helpful in this regard too.

Why not just fill the empty bag while it's around your forehead so you eliminate leakage when trying to get it over your head?

I think, it would be inconvenient for me to do so.
