Hashimoto's: Sounds like you have Hashimoto's Thyroiditis, which is an autoimmune disease. The body attacks it's own thyroid resulting in high thryoid levels initially and low thyroid levels once the the thyroid is "burned out." Sounds like you are currently Euthyroid (in the middle range and ok) on medicine. Your situation and other meds are somewhat complex and might be best addressed with a call-in.
