I came across this book and this work when trying to find help for a family member's Fibromyalgia. What I can to understand is that many chronic pain issues can lead back to some form of a thyroid issue. The most important part was truly understanding what is going on! This book does that. Dr. Johnson lays out a very easy to understand description of all of the problems that can be affecting us if we have thyroid symptoms. Not only that but he shows why you must have good body chemistry so that your body can do what it needs to do. It is easy to see why skipping one of these steps in our physiology could cause a huge list of symptoms. On top of that it also helps to understand why these symptoms may not be helped solely by prescription medications. He does not tell anyone that he treats thyroid disorders and he lets you know that in some cases we may actually need prescription medications while naturally supporting our bodies physiology. I would highly recommend this book to anyone that is looking for the answers!
