I personally think that PTU or Tapazol work best with synthroid being added later. This has been the treatment of some others on this bb besides me. I personally like Tapazol better than PTU because one only needs to take it once or twice a day.
The Mayco Clinic has a book called the Mayo Clinic Family Health Book and it is in most books stores.
Interestingly I browsed this book and saw the person with Graves eye disease and said this is me, prior to my being diagnosed.
