Hello nth humanbeing: Well... personally I've always been more awake at night than during the day. If I allowed myself to do so, I would stay up until 2 or 3 a.m. or so every night. But I try not to do that. Sometimes, though, I find I can't sleep whether I want to or not. Then I do walking meditation... walking slowly throughout the house in the dark. I typically walk for at least an hour... sometimes 2. Typically by that time, when I go back to bed, I go to sleep... or go back to sleep... Under any circumstances though, I try not to sleep too late in the morning, nor do I nap. I also try to keep busy during the day. This tends to "reset" my "biological clock" so that I'm able to sleep that night.
