Gayle interviews sleep doctors and attends sleep conferences only to find out that insomnia is not really being studied. It is a surprisingly common condition that patients don't want to admit, for fear of being dismissed as a hypochondriac.
Gayle Greene equates the suicidal thoughts that result from recurrent insomnia as a legitimate means of "not succumbing" to insomnia. She explains it is a euphemism for killing yourself to escape the hell. One of her interviewees estimates that 90% of suicides are due to chronic insomnia. I did not "succumb" to my personal bout with insomnia, but I can assure you that periods of insomnia are living hell. You remain alive, but feel dead in body, mind, and spirit.
I wish Insomniac had been published years ago. It's a breath of fresh air for sufferers and will be an eye-opening read for the many sleep doctors who don't really understand their patients, the condition, and its devastating consequences.
