Well I don't really think throwing up is always something to worry about, but yeah passing out is. We always keep people awake when they're passing out until they sorta come around (even if takes over an hour). When we do let someone go to sleep, we make sure they're on their stomach so if they throw up they won't choke. Best thing is to know your own body well enough so you don't drink yourself to death (I get to the point where I can't hold a drink anymore, and then I stop drinking for the night) and don't hang out with those people that don't know their bodies well enough.
