I'm awake at four AM because I've been tossing and turning for the past three to four hours with abdominal pain that is localized around the kidneys on my back. I called student health, and if the pain does not subside a little (enough for me to sleep) in the next half hour (I took some ibuprofin as they recommended), I'm going to the emergency room, and if not, I'm going to student health at 8.

Urgh. I'm betting emergency room at five.
