T.F.
I went to see an M.D. Naruropath in Palo Alto, PM me if you want her name. The websites below may help you and the first one has a listing and recommendations for doctors. I was on Syntrhoid and am currently on westthroid. Also, about the iodine, don't start taking it until it's confirmed you need it. I'm hypothyroid and don't need it. They key is getting a doctor or endocrinologist who will work with you. Some GPs are good about this and some feel it's a one size fits all treatment. Best of luck to you and I'll be watching the answers you get. Palo Alto is still a long ways from me.
One last thing, A lot of people are getting into the selling Nutritional products. Some are very qualified but many aren't. I even had a GP refer me to a Massage Therapist for this. Not that the products she was selling aren't good, I just felt she wasn't the best qualified to be advising people. Be careful out there!
