My husband and I have been working to reverse the exact same thing you are going through. My husband had an enlarged thyroid with multiple nodules, he had a giant lump on his neck. We found that a comprehensive list of vitamins are necessary to reverse what's been done to your body. It's been 6 months now and his thyroid shrunk by half within the first few doses of half an iodoral tablet (that was about 2 months ago, he used the liquid-dulse and slowly worked his way up for 4 months due to fear of taking too much iodine) about a week ago now I got him to finally take 32.5 mg of Potassium Iodide and within two days his goiter shrunk almost completely! It's barely even noticeable now, I bet with the addition of a second pill it will be gone completely, we intend to up it in a couple weeks to allow time to adjust to detoxing (doing this prevents the HEAVY side effects).
