slip my friend it sounds like u caught a simple old bug. my advice to you would be LOTS of liquids, sleep if you can but it's not a priority, and throw up when you need to. also if you see a doctor he won't be able to do anything for you but you'll clear up in about 4 days.

i tell u all this cause i just got over something like u described in 4 days drinkin lots of juice and sleeping and puking often.
