Feh, two nights in a row of crappy sleep.
Last night I slept 3:00 to 3:30 and 4:30 to about 6:30.
The night before I slept about 4:00 to about 9:00.
Both nights I was grading and feeling a little stressed, and every time I was about ready to go to bed, I would feel stressed and get another bust of nervous energy.
I graded very slowly, but I did get through a fair number of papers. I will have to review them to see if my comments made any sense at all.
I miss my sleep.
