the docs have found that 1/3 of people on thyroid meds get off of them with iodine, 1/3 are able to cut back on them and 1/3 do better with Iodine but still need the meds. i would imagine that this depends on the shape of the thyroid and other factors such as the amount of exposure to mercury and halogen imbalance. i believe a person can find a way to get the thyroid back up and functioning on its own as long as it hasnt been radiated to a crisp or removed by doctors. even then, stranger things have happened. the mind is your most powerful tool for healing. what you believe is probably how things will end up.
