Written by a noted sleep researcher, it outlines the basic principles of sleep hygiene, presenting practical ways readers can make the changes in behavior and attitude that will alleviate their sleeplessness. The equivalent to having several sessions with a sleep specialist, it should be required reading for anyone who often spends a good portion of the night in fruitless pursuit of the sandman.
