These are voices of a few of the tens of millions who suffer from chronic insomnia. In this revelatory book, Gayle Greene offers a uniquely comprehensive account of this devastating and little-understood condition. She has traveled the world in a quest for answers, interviewing neurologists, sleep researchers, doctors, psychotherapists, and insomniacs of all sorts. What comes of her extraordinary journey is an up-to-date account of what is known about insomnia, providing the information every insomniac needs to know to make intelligent choices among medications and therapies. "Insomniac" is at once a field guide through the hidden terrain inhabited by insomniacs and a book of consolations for anyone who has struggled with this affliction that has long been trivialized and neglected.
