Sleeping Problems?

hugo_pt asks: "I have had sleep problems for some years, but it always get worse in the Summer. Yesterday I slept one hour, so when I got home at 8PM I thought I'd sleep till 9AM or so. Wrong. It's 1.36AM, and I can't sleep anymore. Instead, I'm reading The Complete FreeBSD, and the urge to sleep is gone. I was wondering how many Slashdot readers suffer from this problem, and what they do to combat it ?"
