Sick and sleep

Since Christmas, I've been doing pretty well about going to bed at and getting up at around the same times at night and in the morning. Even on the nights when I was sick and didn't get much sleep, I still tried to get up and stay up, even if I ended up just sitting in the living room not doing much of anything (and sometimes taking an involuntary nap half way through the day).

Well, not so today. I got up this morning around 8:30 (which is still an hour later than I normally get up these days, except for weekends when I usually sleep an extra hour, hour and a half, or so), sent an email off to work telling them I wasn't coming in, because I was up a good chunk of the night with a headache, but fully intending at the time to stay up. Yet, almost immediately, I went back to bed and ended up only getting up just a few minutes ago. And I still feel like I just want to go back to bed again. -_-
