So I've been sick for two weeks, now.
I'm pretty sure the stomach flu (probably a norovirus) is gone, now. For a day or two I felt just fine. Then my sinuses stopped up again, and an infection crawled down into my lungs. My diagnosis is that a new, opportunistic infection has taken hold, probably walking pneumonia, probably one of the mycoplasms that haunted me throughout my twenties.
I'm seriously considering going to the doctor at this point, although I know there's nothing he can do but tell me to drink fluids and rest.
(Side curiosity; why do I get pneumonia at the drop of a hat in the winter? Is it because the weather here is so much more severe than where I was raised? Is it because I live alone? Am I not taking care of myself? Do I just have a weak constitution? Eh, doesn't really matter.)
Drawing and writing is going slowly, but fortunately I have a small buffer. I just hope this doesn't affect my vacation in California two weeks from now to watch the launch of my new satellite. On the other hand, the California climate is just what I need to recuperate. The current temperature here is 8 below. That's not helpful.
