Biphasic Sleep, Day 2
I woke up more quickly today than yesterday, turning off my alarm at 5:01am (Day 1 I didn't get it until 5:10am). The morning was more difficult in general, though--I don't think it's so much lack of energy as the fact that my body still thinks I sleep from 4am to 12pm (as I did before my polyphasic experiment and during the three-day interval of free-running sleep immediately afterward). I ended up taking several short naps during the late morning. I don't think these extra naps are as troublesome as they are in polyphasic sleep adaptation, but it still would be better if I did without them, since part of the experiment is to determine whether I can do with just the 180- and 90-minute blocks of sleep. After the morning naps, I was awake and alert for the rest of the day (with the exception of my scheduled 2:30pm nap). I'm just now beginning to feel a little sluggish, which is a good thing since I'm going to bed in about fifty minutes.
