Thanks for sharing your story with us here. I do have a question for you and your experience. How long after taking radioactive iodine did you feel normal? I had 131I 4 weeks ago and and am still symptomatic. It is wierd because I still have tremors and a rapid heat rate (120bpm) but I am very tired and have gained 5 lbs. in one week. It may be water retention I don’t know anymore. I really can relate to the feelings of helplessness you expressed.
