I'm probably starting my sixth day of feeling a lot more normal, health-wise. (Don't know for sure til later in the day.)

I might have returned to the level of health I was at in mid Dec — which was concerningly-bad at the time, but things got significantly worse after that.

While I'm feeling better, I'm trying to un-decondition my body a bit. Strategy: Walk a few minutes, get tired, and then put myself in a quiet/dark/controlled/alone environment to conduct Optimal Rest
