well, im not doctor (but am a bio major), sounds like you probably ate something that caused this, probably bacterial (maybe staph aureus?)... as long as you dont have bloody diarrhea you are probably ok (keep drinking LOTS of fluids, definitely water and gatorade/ something with sugar, and get some rest). If it persists for another day tho, definitely go see a doctor (who will probably tell you something similar to what I did).

Sidenote: Did you eat a buffet recently?

Edit: If you didnt start diarrhea/puking til the morning, its probably not Staph... probably still something like E.coli or Salmonella, maybe something viral.. either way you are probably ok, but still see a doctor if it persists)
