Personally I don't like SN but I think otc anti-emetics and no acid regulators is prone to failure.
I'm not pro-life (Otherwise I wouldn't be here) But may I ask you what the reason is you wan't to ctb? It makes me very sad to see other people decide to end their life. And some problems can look very dark and impossible to solve, but some situations actually do change. I have seen it myself, people close to me who have been at absolute bottom and now appreciate life, and even though their lives might not be perfect they have a reason to live. I hope this doesn't upset you.
