Biphasic Sleep - Day 6

I went for another 4.5 core sleep, and it's working kind of weird: I spent 15 minutes lying in bed awake before getting up, and was tired for the next 2 hours. But when I come back and take my nap, I stay alert for the rest of the night until 20 minutes before the core sleep, which was impossible with my monophasic schedule. And having extra free time is great :)

The nap was great; and when I wake up after a 1.5 hour nap, I feel less tired than when I wake up from the core sleep, but I guess it's normal since it's early in the evening, and I still have some energy left.
