The New York Times published an article today indicating that CBT can be very effective in insomnia. http://www.nytimes.com/2009/08/11/health/11slee.html?_r=1&ref=health The News is kind of similar to that in ME/CFS - about 30% of people with insomnia significantly benefited from it. It was effective enough in treating this difficult problem that one doctor said it was kind of unbelievable. It appears that it was all about managing your sleep behavior properly; going to bed at the right time (do not go to bed early!), having the environment support sleep, not getting tangled up negative and anxious thoughts about how much sleep you are or are not getting. It shows that in some people this approach works very well.
