Most of the rest of the symptoms are now gone, two days after the main draught of sickness is gone. But I am left with a huge, yawning fatigue.

I can do simple things, like get myself a meal reheated or a sandwich made, or put the case back on a couch cushion after washing it. I can write a post, or play part of a video game level. The effort here isn’t just physical effort, but possibly emotional (though I haven’t had to suppress any strong urges), but definitely includes thinking effort.

But then I need to sit and rest. Sometimes for an hour or more.

It’s galling.
