Whats the easiest way to make yourself throw up?

I don't need lectures, i just need help. I can't do it at all, like fingers don't work... its important to me to know, 10 point best answer to whoever helps.
Update: in all honesty, i know the dangers, iknow how stupid it is, so nothing your saying is new, calling me retarded isn't actually helpful it just make my self hate deeper, so i'd appreciate if you'd stop. Chances of me actually doing it, slim to none.
