Ho hum. Got up yesterday, felt moderately awful, had recovered twenty minutes later so went to work anyway. Got up today, felt utterly horrible, went straight back to bed, and apart from crawling out briefly to email in sick didn't emerge until nearly noon.

Hot baths are very good when you're ill. They're the closest thing to still being in bed that also gets you clean.

Now I feel basically human, though still moving a bit slowly. Probably best if I stay on the sofa for the rest of the day and rest myself thoroughly rather than trying to make it back to work for the afternoon.
