No, I haven't fallen completely off the face of the earth. I am, however, having a bit of trouble getting motivated this winter. A lot of my energy/creativity goes in seasonal cycles, and the winter tends to be one of my lowest times of the year. And unfortunately this year is like any other.
Sometimes I think I would have been better off if I was a bear. I could sleep all winter, crawl out of my cave, go totally apesh!t in the summer, pig out all autumn, then back into the cave for a three-month-long nap. Unfortunately we humans don't work that way, so here I am.
I finally went to the endocrinologist and discovered that I am, indeed, hypothyroid and hypotestosterone. One of the side effects of lithium is that it depresses thyroid functionality, and consequently a lot of lithium patients also take a thyroid supplement to alleviate the side effects. So, I'm still a bit lethargic, still a bit fatter than normal, but things seem to be getting better. I'm still eating fairly healthy, I still exercize 5x a week (I've got Buns and Thighs of Steel, thanks to biking), I get plenty of sleep, and mentally I generally feel pretty well. I'm a little fuzzy-headed at times and feel a bit ADD-ish (bipolar symptoms often look like ADD), but overall I'm okay.
I promise I will post a real update to this thing very soon (probably more tales of the various meds I've been on over the past dozen+ years). So don't say I didn't warn you.
