I have known for one month that I have hypothyroidism. I immediately went to Borders to look at books. After an hour of looking at all the books covering this, I came home with yours. I have had no desire to purchase any other books, because yours is so comprehensive. I have learned so much. Tomorrow, I go in for my one month doctor visit. I am prepared with my list of questions for the doctor. Thank you for empowering me with such a wealth of information. I definitely feel like I can be a partner in managing my own health. Thank you -- Terry B.
