To expand on PGs comment a little bit. I used to have serious problems with onset insomnia, almost to the point of making me sick. While trying to find a solution, I found that having a few quiet, "boring" hours before I go to bed helps me a lot to fall a sleep earlier and quicker. This means no tv, no internet, loud music etc. At first, this was extremely frustrating for me, I felt that I needed some kind audio/visual stimuli to keep sane. But after a while, I started to embrace this boredom and focus my awareness inside. Sometimes I meditate, write in my journal, take a slow walk to a beautiful viewpoint or just chill out to an old Bob Dylan album and really try to focus on the music. These days, I manage to do this about half the time, and it usually makes me calm enough to fall asleep within 30 minutes or so.
