If I were to take a combination of xanax, methadone, and maybe a shot of vodka (for good measure) what are the chances I'd live? How much would someone with a BMI of 17 have to consume to for sure die? Would I die in my sleep or would I feel myself stop breathing? And, if I were to live, would I suffer brain damage? Psychosis? From what I've read so far it seems like a pretty peaceful way to go.
