> On the original topic: my circadian rhythm wants to run either 30 or 32 hours. In my teens and early 20s I had the same. It was fine most of the time, and then I'd crash and miss a day or two. Then I started taking midday naps, whether or not I feel like I need them. Well, it started out that I'd fall asleep in 2:00 lectures, and I noticed that it was some of my best sleep. Weirdly, napping a little (5-30min) during the day helps me sleep at night. When I miss it, it can be impossible to get to sleep -- right around bedtime I suddenly go from normal to buzzy and if I try to force it I just wake up more.
