Turns out I wasn’t just Entirely Exhausted last night; I’d been poisoned by being sold decaf instead of regular coffee.
My head started hurting mid-afternoon; by the evening it was really hurting, and not responding to Advil; I went to bed early(ish) and tried to read, but my eyes ached, so I just went to sleep; I woke up a jillion times in the night, my head just pounding; this morning I threw up.
Went back to bed and slept till past 11, then got up and tried some tea (CAFFEINATED tea), and started feeling a little better… had another cup of tea and some breakfast, and felt better still… by an hour later I was thinking about maybe going for a swim; an hour after that I did, and it felt great.
Then I worked on Hobgoblin (I’m back, once more, to where I’d left off; I think I’m ready to move actually forward again!), and watered the garden, and made a nice dinner… I feel all recovered now, except my head and neck feel like a herd of buffalo stampeded through them. And I’m tired. But in an ordinary, going-to-bed-to-read sense.
Evil, evil decaf.
