A new study published in the Archives of Internal Medicine shows that cognitive behavior therapy works better than prescription drugs for insomnia. Drugs can only be used for a limited time, after which insomnia returns.

Therapy takes 2.5 hours over a six-week period and often cures insomnia. It includes well-known instructions about going to bed and getting up at the same time plus relaxation techniques.

In his book, Say Goodnight to Insomnia (Henry Holt), sleep expert Gregg Jacobs of the Sleep Disorders Center at Boston's Beth Israel Deaconess Medical Center gives the entire course.
