I've seen videos of death from SN - and I wouldn't want to die like that. It's painful. Discomfort, nausea - I've had enough of that in life; at least before death, I want to feel comfortable. I also refused the propofol I have - it's too complicated. I think the best option is inert gases. Difficult? A bit tedious, but not difficult. Jumping from a plane without opening a parachute is a good method, but I want peace before death. I'm leaning more towards a strong overdose of opioids, but that method doesn't seem reliable to me. Taking a large amount of sleeping pills, like nitrazepam and zopiclone, seems very good - I have a lot of them. Do it in the cold, in winter, in the forest. A little later, remove outer clothing. Cold + coma is a powerful tandem. Despite the sleeping pills, the cold in turn also suppresses the central nervous system; hypothermia multiplies each effect. Granted, hypoxia and other destructive processes slow down, but that no longer matters, as for death - it's inevitable.
Hypothermia itself is very dangerous because it quickly suppresses consciousness and plunges you into sleep. I remember a story: In December 1980, in Minnesota, 19-year-old Jean Hilliard was driving at night on a country road. There was a severe frost, temperatures ranging from -22° to -28° . The car skidded into a ditch, veered off the road, and stalled. Jean was dressed normally, not drunk, not sick, not exhausted - there were no preconditions for fainting or feeling unwell. She got out of the car and decided to walk; she needed to go about 1.2 miles. That distance takes about 20 minutes. Considering she stepped out of a warm car in winter clothes, she might have started feeling the cold after about 10 minutes, unlikely sooner. She walked confidently, wasn't freezing, and felt normal. But at some point, almost there (literally 4-5 meters from the porch), she suddenly lost consciousness and fell face-first into the snow. Without any warning - just blacked out. She lay unconscious all night - about 6 hours in the open air in the same severe frost. When she was found in the morning, she was completely frozen: her body was stiff as a board, her pulse and breathing were practically absent. She survived. But why mention this? This story is a classic example of how hypothermia silently and very quickly "turns off" consciousness, even if the person felt absolutely normal and was in a sound state up to that moment. She didn't even have time to realize what was happening - she just walked, walked... and that was it.
This story clearly shows how insidious and swift the cold can be. It would be a calculated move. Take the sleeping pills - a sufficient dose to turn off anxiety, fear, and the struggle. And the cold will do the rest. It will become the accomplice that guarantees there is no way back.
This is a method that doesn't require complex mechanisms, outside help, and from which you don't expect unpredictable results.
