Yeah, I think there’s a list of ppl who used SN and if they succeeded or not.
It’s possible but it’s gonna be less peaceful and you might have to try more because you are more likely to throw it up, so that means you’ll have to drink more
I think it's different for everyone, some throw up with meto, some don't throw up without it, I guess it's a bit like some people can drink a bottle of whisky and not throw up, others feel nausea after a glass of whisky.
It all depends on you and the strength of your stomach.
There's a search function and resources. Although I wont lie, I too have asked a million questions about SN, just in case. Anyway to sum it up : It's disgusting, you have to be starving, you'll throw up, your heart will be pounding.
