I've noticed that you have not mentioned anything about supplementing with iodine. If this is the case then it may be something to look into. http://iodine4heath.com is a good website to begin finding out about the many things that are related to IDDs (Iodine Deficiency Disorders). There is also an Iodine supplementation forum here at curezone.com
"From 1900 to the 1960s almost every single U.S. physician used Lugol (iodine) supplements in his or her practice for both hypo- and hyperthyroid, as well as many, many other conditions—all with excellent results. In fact, Iodine was considered a panacea for all human ills. (1) Today a phobia—generated by medical misinformation against Iodine therapy—has caused physicians to avoid this powerful treatment like the plague. (2)
By avoiding iodine therapy, you could be missing out on the very link that could get you well. Today we know that total body iodine fulfillment or sufficiency can finally resolve tough, stubborn problems that resist all other treatments. Called orthoiodosupplementation, this treatment employs elemental iodine supplements until the thyroid gland and all other iodine-sensitive sites in the body have reached iodine sufficiency.
The most commonly difficult problems for which this therapy has been called a panacea are fibrocystic breasts, polycystic ovary syndrome, hypo- and hyperthyroid (with or without goiter), brain fog, constipation, obesity, diabetes, hypertension (high blood pressure), and even some heart problems—most notably irreversible arrhythmias like atrial fibrillation."
