Extra strength Tylenol = great for suicide?

Oddly enough my chiropracter was talking about people who use pills daily to get rid of pain and only wind up fucking up their kidneys or liver in the process. And then he says taking an entire bottle of extra strength Tylenol is for the people who are serious about suicide because it fucks up your liver and there isn't a way to help you soon after you take it.

I trust the guy isn't lying, but does anyone else know about this? How long does it take to kick in? I plan on having a backup way out if this gang I know that wants me dead comes knocking on my door. I'd rather die like that then be gang raped and stabbed to death. They don't use guns, otherwise I'd opt for getting shot instead. Being hacked up doesn't sound like much fun.

I'm not looking for a peaceful or painless death, just a guaranteed one. Watching them literally fuck up the woman you proposed to, and then saying you're next kinda makes me just want to get it over with if you know what I mean. No need for drama, just quick and effective is good. So does Tylenol do what my chiropracter claims? I can't exactly go to my doctor and say "Hey doc, you wouldn't happen to know if taking a bottle of extra strength Tylenol would kill ya for sure, would it? I was just, uh, you know, wondering."

Most suicide attempts by overdose fail. Why? It takes a very long time to die from an overdose of a substance such as Tylenol, so someone might stumble upon said suicidal person. Also, it isn't painless. Quite the opposite.

Go ahead and overdose on Tylenol. You won't die, but your life will be much worse afterwards. But by the sound of it, you don't really want to die, and just want attention. So, yes, I guess this would be a great way to selfishly draw a hell of a lot of attention to yourself.
