In my case, I stick around because even after doing extensive research, I just can't find a perfect method -- one that's reliable, relatively quick and painless, does not present a physical danger to others, does not require an advanced degree in engineering or chemistry to execute, where the instruments are readily available (i.e. you don't have to break the law or drain your kid's college fund to get them), and where the consequences of failure aren't devastating. It would be a supreme irony, to say the least, to not only fail at one's suicide, but to end up an invalid or in the can, or both. Plus, virtually all methods leave an awful mess, totally inconsistent with the dignity of (theoretically) regaining control over one's fate: many poisons cause abundant vomiting; muscles in the nether regions of one's body relax immediately after death causing your wastes to exit spontaneously (being delicate here). I guess I still care about life enough that I don't want my husband to find my corpse marinating in such a cocktail. (As for merely finding my corpse, I think it would do him good to finally listen to me for once.) Plus, I lack the willpower. It's as simple as that.
