Insomniac

No one can describe a journey better than someone who's made the trip, and insomniac Greene's exploration of the disorder is both fascinating and disturbing. Many people, including doctors and insomniacs themselves, believe that sleeplessness is the patient's fault: too much caffeine and stress, irregular bedtimes, lack of exercise. In fact, no one knows what causes it, but the effects of insomnia are clear: as Greene, a professor of literature and women's studies at Scripps College, shows, sleep deprivation kills creativity, reduces levels of the hormones needed to repair cells and is directly linked to weight gain and memory loss, high blood pressure and diabetes. Insomniacs are usually referred to mental health practitioners or the growing number of sleep labs offering behavior modification or drugs (which, for Greene, have always “buil[t] tolerance, and rapidly,” necessitating ever-larger doses). “This is a somewhat cranky book,” Greene admits, and rightly so. “You can't live with this problem as long as I have, you can't be blown off and written off as many times as I have, and not get cross.” Supplementing her own experience with that of other chronic insomniacs and a look at the science of sleep, Greene offers an enjoyable and informative account that will provoke even readers who get their full eight hours a night.
