I've been up for 12 hours on four hours of sleep. (I have sleep issues nowadays.) I'm sleepy and exhausted, but I'm about to give a lecture on college-level mathematics for two hours. Coffee hasn't been very effective so far.
Wish me luck. I'll report back afterward with the results... if I don't pass out.
