Query: Empower yourself with this book

If you have hypothyroidism, you need to KNOW the facts which means not just seeing your dr. every 4 months. This book is a wealth of knowledge. I recommend reading it, her website and any other thyroid books you can get your hands on. There are several at Amazon that I have read and reviewed. Knowledge it power. Know your disease.
