I managed to stay awake (physically, if not necessarily mentally) last night until sometime around 9pm. Then I gave up the struggle and hit the bed. It took me dozens of seconds to fall asleep, and, though I did wake up once or twice during the night, I basically slept until 6am, just before the alarm was ready to sound off. I’m still in a bit of a fog, but it’ll do for a quiet Friday morning at work.
