In a word... CRAP!

I didn't get much sleep last night as I woke up with much lower GI unpleasantness. I've had to cancel a visit with my nephews and spend my last day of vacation at home, where I am preparing to give the graduate student Qualifying Exams tomorrow, starting at 8:00am. I cannot reschedule them, so I'm gonna have to get through it. I could ask the committee to proceed without me, but I will wait and see how I'm doing later on before making that decision. This sucks!
