Apparently half a degree makes a lot of difference
The day off -- or to be more specific the take-it-easy-so-if-I'm-sick-then-I-can-get-better-quicker day -- seems to have worked. Seems. I hope. I'm definitely at a lower temperature. The thing is, I usually run a little cool; 98.6 degrees F is rare for me. I was close to that, and that plus feeling on the verge of lousy were my signs to cool it. Literally and figuratively. Which, again, seems to have worked.
