At this time of year I always find myself sleeping more, and wanting to go to bed earlier. I know it's the ancient cycle of seasons at play in my body—as the days get shorter, there's historically less and less reason to be awake. After all, there's not much hunting, gathering, or repairing of tools that one can do in the pitch black (did tools come after fire? Probably . . . but then, I'm no historian). Anyway, I've been finding myself yawning and thinking about bed at around 8:00pm the last few nights. I make myself stay up until 10, but then I'm plenty happy to go. I stayed in bed until 9:30 this morning, too. I know part of it is simply chemo fatigue, but a lot of it is the season change (strangely enough, once winter really hits and the days are incredibly short, I find myself wanting to stay up until way after midnight.).
Of course, the financial markets and the political scene are enough to make anyone want to hibernate for a while anyway.
