Lately I've heard about this stuff a lot, and apparently it's kind of common?
Anyway, I think it sounds kinda cool.

Does anyone have any experiences with this? As in, did it really make you unpoisoned? Or did it taste absolutely horrible or etc.

Uhh. I have never tried it and I wouldn't want to try it.

Isn't it the drug bulimics used to induce vomiting?

Yes, but I'm definitely not going bulimic.
pixiedust! = revoltaire
blahblah..

It empties your stomach if that's what you mean by "unpoisoned" but it tastes like shit.

How long does it usually take to vomit if you take, maybe two tablespoons?

If syrup of ipecac is that nasty, I'd hate to know what charcoal tastes like. Apparently charcoal is supposed to be grosser than ipecac.
