Doctor update:

She says she'd agree with the food poisoning (bacterial gastroenteritis) except that there's a sudden rash of (apparently viral) gastroenteritis in Fort Wayne. 6 admissions to Parkview, 6 to Parkview North, all for acute dehydration due to vomiting and diarrhoea. I, on the other hand, am not dehydrated. Go me. Clear liquids and Gatorade for 10-12 hours, not too much at a time, then rice and toast and applesauce until I feel better. Should be okay tomorrow morning for the exam... I'm going to go nap, then study more.
