same shit happened to me.
im 16 as well, and went partying with my brother (a freshman at college). drank way too many, and also had some 96 proff stuff before i started downing beers, i think thats what got me throwing up. i dont remember how i got home, but my brother said i threw up like 3 or 4 times. i woke up in my own puke as well. not fucking cool. i spent all of saturday cleaning that shit up.
i also woke up still drunk, and had to go to a lifeguarding course, i got there an hour late and it lasted for 9 hours (8 for me)
