[EX Q]: Betrayal of Trust . I received what looked like a nicely preserved used copy.   The book literally fell apart from the binding the first time I read it. It continued to come unglued from the binding each time I attempted to read it.   Not a good quality copy.   Would not purchase from this supplier agai
[EX A]: NEG

[EX Q]: Don't buy anything by this guy . This guy is a convicted felon and crook.    Note: all positive reviews only have one review in the history.
[EX A]: NEG

[EX Q]: Really bad book . I don't know who wrote the 5 star reviews of this book, but they're like those actors in bad TV ads claiming that they lost 100 pounds in 8 weeks. Those rave reviews are hard to stomach. This is a really bad book--I agree with the person who said that they would give it zero stars if they could (half the book IS empty blank pages for your journaling). There is not much that's helpful in this book. Much better and thorough are (1)  The Thyroid Solution by Ridha Arem, (2) Living with Autoimmune Disease by Mary J. Shomon, & (3)Thyroid Power by Richard L. Shames and Marilee Halo Shames. These books are better researched and are compassionately and well-written by M.D.'s and/or persons with personal experience with thyroid problems.  Skip this book by Dirgo
