Sorry, PN is potassium nitrite and SN is sodium nitrate (not nitrates). To clarify, I am making three cups of mixtures. The first will be SN and water and the second and third will be PN and water. In case I can't keep the first cup down, I just want to make sure that using PN (after I have already drunk the SN) is not counteractive to the whole process.
SN is sodium nitrite, not nitrate. I'm guessing you just made a mistake and wrote it wrong, but I want to make sure.
Honestly, this is the first time I see someone intending to use these two substances together.
I have absolutely no knowledge on this subject and I don't know how these two substances interact with each other.
But my intuition tells me that this is not the best idea.
I don't know what might happen when you do this and how your body will react.
I also don't know how exactly PN works.
It would be best if you created a separate thread and asked this question.
However, according to my limited knowledge, using these two different substances together for CTB is not a good idea.
Of course, you may not need to drink a second glass and 25 grams of SN will be enough.
Even if you vomit, it doesn't necessarily mean you've failed.
