So at 3:00am-ish this morning, I had the interesting experience of waking up in severe intestinal pain combined with nausea. Attempts to not be sick failed quite thoroughly at 5:30a.
I'm feeling really sick right now- I don't feel like giving full details- but the summary is a visit to the infirmary and then getting carted home by my parents, and my getting excused from this evening's Calculus exam.
At least the diarrhea and nausea have mostly retreated. But I still feel really, really sick.
