Sleep. I could probably use more. I've been on vacation for about seven weeks now, and somehow I'm only barely rested. I'm not sure if going back to work next week is going to be good or bad for that. A regular schedule is actually kind of good for me, because I only actually feel like working around the house when the sun is up. Interestingly, I can work on the computer any time of the day or night, so my choice of occupation was probably a good one.
The problem is not that I can't sleep. I almost always fall asleep very quickly, and once I'm out it's hard to wake me up. Even if I do wake up, I can generally go back to sleep fairly easily.
No, the problem is, as I've long known, that I hate change of state. I hate going to bed. I think it's a form of laziness - it's significantly less work to keep playing on the computer than it is to go to bed. By the same token, it's significantly easier to stay in bed than it is to get up. The difference is, I go to bed when I want, but I have to get up for school or work, which is outside of my control. I'm fairly sure it's a form of laziness, because the more tired I get, the less inclined I am to go to bed. That there is an unlimited amount of stuff to read on the web doesn't exactly help the situation either - there will always be "one more" interesting thing to read.
I also know from experience that if I do let my sleep schedule drift, it tends to drift until I'm going to bed around noon and/or getting up around midnight. Somehow that seems to be the point where things stabilize, which seems a bit odd. Since I can stay up long past any usual "bedtime," and work on something longer than a 24 hour day, I'm not sure why it stabilizes at the most awkward possible schedule.
So, while my vacation has been relaxing, it hasn't necessarily been restful.
Possible courses of correction:
*Brush teeth two hours before bed, when I might still have the energy
*Take the laptop to bed so I can do stuff, but not expend much more energy than closing it when it's time to sleep
*Convince myself to go to bed on time like a responsible adult (ha!)
I think it's good that I stay away from drugs and alcohol entirely. It's much too easy for me to do things before I go to bed and regret them in the morning.
