Interesting experiment. I usually donít agree with sleeping this way, but yesterday I slept an hour in the afternoon, then I stayed up all night and Iíve slept from 5:00AM till 10:30AM. I woke up a little dizzy, but I felt great for the rest of the day. My time now is 21:43PM and I still feel great, not sleepy and not planning to go to bed early. Iím not sure about how healthy this is, though. I didnít sleep in the afternoon today.
