Help Help with KN method (URGENT)

[koka]

So, now, I have KN (potassium nitrite) with me, I purchased it from real chemical manufacturers who sell lab products, it is 95% pure, but how does this work, like, how does it taste, I know that you need to take around 30g or more for it to work, but, which antiemetics do I need, I think I can easily ondansetron but metoclopramide is kinda hard to obtain, how much antiemetics do I need? What should I do if I somehow vomit? I have 7.5mg xanax, and around 3mg clonazepam and even 140mg of zolpidem so I can use those as well, my BMI is 13.6 sp less buffer, idk if that helps, please help me
