Sleep, don't sleep.

Life has been winding down.

I can't sleep, or I wouldn't still be up.

I've been increasingly getting the feeling that I have insomnia. However, the sporadic times when I can't sleep at night happen usually when I've slept all day, so it's hard to keep track of when i really don't need sleep and when I need sleep, but can't sleep.

I suppose I could keep a log, but I've tried and it's hard to pinpoint exactly when you went to sleep unless you are a clock watcher.
