Mood/energy tracking stuff

Because I have bipolar, I like to track depression-like symptoms here. The last several days, I've been sleeping a LOT more than usual -- crashing out in the middle of the afternoon, and thereby losing half-days I could be using to Do Stuff.

On the other hand, my other two depression markers, mood and motivation, AREN'T lowered. I'm ANNOYED that I'm losing half-days to sleeping, because I WANT to be doing things, and "wanting things", ESPECIALLY "wanting to do things", is one of the things that goes away in my depressive episodes. I also don't have any depressed mood -- I'm quite capable of enjoying things, and am not having any generalized malaise.

So, my working theory right now is that I'm NOT in a depressive phase, and am looking for other possible causes and solutions.

I have been thinking about nutrition, for instance -- more protein in the mornings might give me more energy over the long run. Or perhaps I should be using stimulants, such as tea or coffee -- I know that those are things that many people use regularly to control this sort of thing, and they're easily available, socially acceptable, and generally have relatively few serious side effects in the amounts typically consumed. Plus, I actually do LIKE tea and coffee.
