Is it really insomnia if I'm not tired?

Since school began, I've been having trouble staying asleep. Oh, sure, I go to bed at 10-ish, maybe do a little light reading, then go to sleep. But my body has been waking itself up at extremely early times, often around 3:30 or 4:00. My alarm is set for 5:00, but I don't think I've had the chance to let it ring all year so far (with the exception of last Saturday, when I had to be up to get to Sylvan). This sort of thing usually only happens if I've had too much caffeine late and/or I take a nap during the day. But I haven't been doing that. Nevertheless, I've been doing just fine, getting all my work done, actually being productive during my prep time, and not hitting the couch as soon as I get home. I'm expecting to hit the wall any moment now and get a sound night's sleep, but it doesn't seem to have happened yet.

On a plus note, I think I finally got Grade Machine up and running to the point where I can just update it when I have new scores I have to enter, and not worry about updating or tweeking it as well. For those who don't know about it, Grade Machine is a terrific computer program — locally made — that can do all the functions of a grade book, withot all that tedious mucking around with actually doing the math. I learned how to use it a few years ago when I was teaching part-time at Lake Washington High School, and I'm glad Marysville uses it as well. Tonight, I use it to make some badly-needed seating charts!
