Intermission, Day 2 (Free-Running Sleep)
Day 2 of my free-running sleep trial is running very late. I just don't feel tired yet. It's not a distressing fact, though. I got in bed earlier and listened to music (the first five tracks of Wide Angle by Hybrid), which I found incredibly relaxing. I thought I might fall asleep for the night, but instead at the end of the fifth track I felt like getting up.
There's really not much more to report about free-running sleep. The next time I go to sleep--sometime in the next couple hours, I think--will be my last unregulated sleep before I start biphasic sleep.
