Old habits are hard to break.
I was reminded just how right they are. However, being aware of the effects of jet lag, I did not let myself go to bed until about 10 p.m., hoping that if I was tired enough I would sleep through the night. But as tired as I was, I woke up about 1 a.m. and knew I wouldn't get back to sleep real soon. Knowing I had a full day ahead of me, I got up, took a sleeping pill, read for about an hour to give the pill time to take effect, then turned off the light and laid there trying to get back to sleep. I don't know how many fitful hours I laid there in the dark, but I did manage to get to sleep a little before the alarm went off.
