Last night, I was exhausted. I went to bed early. Woke about 9:30, 10:30, 11:30....3:00, 3:15, 3:30, 4:00 - 4:30, 5:00....
Don't know what I did wrong. Strained my back a little, hauling a heavy typewriter up the basement stairs for initial testing (inconclusive) and then back down again, but that's pretty much par. Clearly, I need more practice!
