Nap

I didn't fall asleep until the last three or four minutes of my nap at 7.  I still feel okay, but I'm not sure I'll be able to really fall asleep at that time with the amount of core sleep I have.  My first idea was to cut my core sleep down to 3 hours, but I think I'm going to give myself a few more days to see if I can learn to fall asleep faster.  I kept getting some really intensely deep waves of sleep at the very end that only lasted a few seconds each.  But it's now 10, and I'm still running fine on those few minutes of intense sleep.  This is utterly fascinating.
