DID NOT READ/DO NOT RECOMMEND
Avoid this book if your insomnia is caused by physical issues. Seems to only be useful for those with sleep anxiety.

I've never rated a book that I haven't read before. This time is a first. But I feel that it's important. I read an article that summarized a few of the tips from this book and it angered me, so here you go.
The book says things to the effect of [I'm paraphrasing]..."there is no conclusive evidence that lack of sleep causes health problems." And "no matter how little sleep you get, you will still be able to get through your day, stop worrying about it." <--THIS IS A HUGE PIECE OF BULLSHIT IF YOU HAVE REAL SLEEP PROBLEMS.
I don't know what evidence (if any) the author presented as I didn't read the book, but there are NUMEROUS studies showing a lack of sleep can cause heart disease, obesity, impaired driving, etc., etc., etc. And if impaired driving is an effect of lack of sleep, then how in god's name can he claim that anyone "will get through the day just fine" in spite of not sleeping??????
It seems that much of the book deals with those who have what's called "sleep anxiety" and that is indeed what the author of the article I read had. However, sleep anxiety is not a physical disease. By saying sleep problems are due solely to not being able to relax/stop thinking (i.e. telling us it's all in our minds), this book is a disservice to those of us with real physical diseases who cannot solve our sleep issues simply by "positive thinking". I probably would have paid money for this book, thinking I could find tips to ease a few of my sleep issues (although I know I can't solve them completely), and I would have been upset and angry at the lack of useful information in there. That's why I'm writing this "review".
Looking at the other reviews here on Goodreads (and from what the author of the article I read said), it seems that even for psychologically caused sleep issues, these recommendations only work some of the time.

Note: I have fibromyalgia and chronic fatigue, unexplained by any other health issue. I have been examined by many doctors, including a neurologist, and several psychiatrists, including a sleep disorder psychiatrist. The sleep psychiatrist proclaimed my "sleep hygiene" as being well within accepted norms and that I had no psychologically caused sleep problems. My psych eval/treatment consisted of doing a lot of the things it looks like this author recommends in this book and none of them worked at all for me and I'd tried all those tricks many times before looking for relief. I've also had a sleep study done, and was told I have no physical sleep problems they could find (sleep apnea, narcolepsy, etc.).
