This is a must read for education about your thyroid. Mine was removed 8 years ago due to large goiters and Hashi's. I am now armed with education on how the medication works and what test I should ask to be run. My only regret is that I waited so long to educate myself about this topic. Mary is a very educated authorty and I really apreciate her efforts for al of us. This book is well worth the time, as are all of her books on the subject. Thanks so much for awesme prices iherb and great, fast service.
