I have this problem, where the idea of "going to bed" is often synonymous with "giving up on the day."
So I'll be really tired, and not really have anything productive I could be doing, but I still don't want to go to sleep.
Maybe once I'm actually in the bed, I'll feel better about going to sleep.
I was looking for a piece of music relating to sleep (other than the Eric Whitacre, which I love, but I was looking for something I'd not heard before). I found this, and I like it.
