I am scared of failing with SN

[golfmavenice]

I have every drug needed:
2x500 mg paracetamol(pain killer)
3x10 mg metoclopramide(antiemetic)
4x20 mg famotidine(antiacid)

Fasting for 13 hours

I have 1kg of %98 pure SN

But I am still scared of vomiting all of the SN or experiencing suffocation. I know if I absorb 1/5 of the SN I will die if not found in first 8 hours but I am still worried.

Is it possible for me to puke all of the SN even after ingesting all of these drugs?
Do people experience suffocation?
I read PPH. But I shouldn't know if I should trust PPH

I read SN successful and unsuccessful attempts and some people say that they experienced gasping for air and some people didn't lose conciousness after 1 hour

Where did you find that people suffocate ?
I've heard only of heavy breathing.
