I went to bed at 11 like I was supposed to. Then I got something in my eye, and it took me half an hour to wash it out, and of course that thorougly woke me up.
Then I woke up a little after 5, with my body still very tired, but my mind going in circles at 90 miles an hour. I gave up and got up a little after 6, almost an hour before my alarm went off.
We'll have to see how well I manage to get through the day.
