The New York Times has another interesting article on sleep. I believe the author has the right idea about not relying on medication to try to get to sleep. He was helped by the professionally developed material on the CBT for Insomnia website. Undoubtedly they have a lot of helpful information, but it is expensive.
Although helpful, I still believe professional sleep specialists are missing a big piece of the getting-to-sleep puzzle, and that is the recognition of the nature of hypnagogia and a directed approach to get you through it and to sleep. This is what I present in In Pursuit of Sleep, which I am currently writing and hope to publish within a couple of months.
