Before I turn into a pumpkin...

I really should go to bed. I don't know what it is, but lately, I just can't seem to go to sleep early, and even when I do get in bed, I read for an hour or two, don't fall asleep. I still have that feeling that I had when I was a kid that the grownups are awake doing all the fun stuff while I sleep. I don't know why its so hard for me to get to sleep, even when I am sleepy a part of me fights the sleep. I had a nice routine this summer, going to bed by 9.30, and I couldn't keep my eyes open for much longer than 9.45, really. Now I hardly feel like the same person. What happened to summer-me? Burnout on sleep? Huh?
