This is hands-down the best book for fibromyalgia sufferers that I have ever read. All the other books have different theories about the underlying cause, and there is always something about them that doesn't seem quite right. This is the only one where every symptom clicks and every treatment and experience I have had so far fits exactly into what the author describes. There is a lot to take in, but the author does her best to keep it simple for us non-medical types, while also providing hard evidence for everything she says. I highly recommend this book!
