[swah]

I can sleep 6~7 hours most nights and never wake up rested and energized. Usually I attribute this to getting older, but then once every couple months I wake up feeling like a young guy, full of energy... and can't really trace that back to diet or caffeine intake easily. Next thing I plan to try is some kind of optimism... I'm naturally a melancholic, a pessimist, like always thinking about the worst case kind of person and wonder how much all that worry (health, kids, savings, job...) affects the sleep.
