Biphasic Sleep, Day 15 (Day 5 on the revised schedule)
Ati: Yeah, I need to work on that self-discipline bit--today I woke up at 5 am and decided to take a 25-minute catnap...which was followed by another catnap, and another...Now at some point in this string of catnaps, I decided, "Whatever--since I can't seem to get up, I'm going to get my 3-hour nap now." I didn't set my alarm, as I realized when I woke up some time later, yet when I looked at the clock, the nap had lasted just under 3 hours.
So the four sleep cycles are definitely ingrained in my body at this point, and judging by the fact that I wake up before the target time so often, I would say my sleep cycles are already a little bit under 90 minutes. The only obstacle left--and it's a big one--is to use self-discipline to force some consistency into my sleeping habits.
Maybe I'll go back and read Steve's
self-discipline series again (which is, coincidentally, the very first thing I read on this site about eight months ago).
