This is basically me every night. Unless I go to bed at 3am, I usually toss and turn for an hour or more. So, I listen to audiobooks. Nothing heavy, usually just sci-fi or fantasy. Basically cotton-candy for the mind. Unless I have a good lecture going, the Great Courses stuff is soothing. But, that usually distracts me enough that I finally fall asleep. I use a single ear bud in my right ear and set a sleep timer so that the book shuts off after a reasonable time. That usually gets me close enough to sleeping that I can finally get the rest of the way.

The only downside to this plan, is when you get a really good book, with a good reader and you start getting towards the end of the book. The temptation to go just one more chapter is hard to resist.
