This book sends some very bad messages. It does not explain how the course of fibromyalgia can be mild, moderate, or severe. Some people with severe FMS have incapacitating pain. This book implies, that, if you have incapacitating pain, you are 'just giving into it', and 'you need to find better ways of dealing with your pain than laying in bed'. Unfortunately, people who do not have FMS read books like these, and get the wrong messages about people with severe FMS. I would not recommend this book.
