Saltine crackers and 7up. always does the trick for me..
try eating oranges which contain vitamen C which should help or if that does not work try pepto
drink gegerall and like eat small not alot
and losts of water can help some times and some kind of mecone for the day so you stay wake
drink a 40! make that a couple 40s.. then you'll puke, and feel like crap.. but a different kind of crap.. and you won't have to worry about puking at the party because you will have already puked up everything in your stomach.
