at work already, again

Since 7:15 appears to be the magic wakey time, last night I went to bed before 11 and managed to get almost eight hours' sleep. I wake up with a high heart rate, and there's no way I can go back to sleep. I figure it's a combination of seasonal affect change and situational stress, and I can compensate for the seasonal part, at least, pretty easily. Of course, today is when my head and joints have chosen to hurt in response to being short on sleep. Tell me again why I try to take care of you, body.
