I had RAI aa year ago this month & it almost killed me. It did nothing to reduce my thyroid levels, I had hives, lost of taste (could not taste anything), more rapid weight loss. Ended up in hospital for anorexia. Lost alot of hair, very weak, severe arthritis, I did not have before.
There is no way I would reccomend RAI to anyone.
I now take Avemar live enzymes, Live pro-biotics, Natural Vitamins ect. and am finally starting to feel better again. I highly reccomend the natural approach. I too took Methimazole, Propranalol ect. and it did not work.
