My sleep is segmented. I go to bed around 9 because I'm exhausted. I awaken around midnight and stay up for about an hour. Go back to bed and sleep. Wake up around 4, stay up for an hour or so, go back to sleep. Awaken around 9a.m.. By mid-afternoon I'm falling asleep and have to lie down.
After the afternoon nap I'm up. Seems I would be not tired enough to sleep around 9, but I'm so tired I fall asleep right away.
I wish I could just sleep from 10p.m. to 9a.m. and stay up until 10p.m., when I go to bed again. But it just doesn't happen that way.
