While experts' common-sense recommendations about sleep hygiene should be the first line of defense against insomnia, selectively breaking them can sometimes help, too. TV isn't recommended, for example, but a DVD or show (make it a boring one) may put some people to sleep. "Listen to experts' rules; don't throw them out," says Gayle Greene, a lifelong insomniac who has learned to cope. But "bend them, make them work for you."
