I have read several books about fibromyalgia and chronic fatigue. They were, in general, clearly written and their theories were clearly espoused. This book has almost no theory, (you must buy the previous book, only available used) and the content was repetitive and poorly organized. A perusal of the author's website will give you all the information you need to use this protocol.The theory of this book, using guaifenisin for fibromyalgia, has been much discussed on the internet; and the upshot seems to be that the placebo effect is a powerful force in medicine. I am sure Dr St. Armand fully believes in his treatment, but the science does not bear out his theory.I too, am looking for relief from pain, but I would save my money on this book.
