Although the catchy title may mislead, this is a serious encyclopedia of sleep disorders. Based on sleep disorder studies from the Mayo Clinic's insomnia program, of which Hauri is director, this book goes into precise detail on the many kinds of insomnia, incorporating the complete range of research and treatment in easy and accessible language. The core of the program is record keeping, and the book discusses the sleep and day logs that patients often must keep for weeks before the particular cause for the sleep disorder is discovered. For consumer health collections, this is the best book this reviewer has seen on insomnia. Highly recommended.-- Evelyn L. Mott, Palm Beach Cty. P.L . , West Palm Beach, Fla.
