I was down for the day – literally. I think I slept something like 16 hours all today today – way more than usual for me. Karen thinks it was because I finally relaxed a bit this weekend after a busy summer, and everything caught up with me. I don’t know what it was, but I was crashed all day. I don’t feel any worse the wear for it – and in fact, I’m kind of tired again now (nearly midnight), so I guess I clearly needed it. Weird how those things happen – I wouldn’t generally be able to sleep again so easily after having that much sleep recently.
