Estivation

Aargh, I have got to stop sleeping this late. I'm supposed to be rolling over onto morning shift next week, and my sleeping patterns keep drifting in the wrong direction. But, man... You know how sometimes, in the winter, your body does that thing where it just wants to eat a lot of starches and curl up in bed and sleep? I seem to get that at the height of the summer, as well. I wonder if I have, like, the opposite of SAD. Is it possible to get too much sunlight? I know I often find myself wishing the damned sun would hurry up and set, but that's mostly just because it's so freakin' hot.
