ok, sorry, I think you just meant hypothyroid. I didn't have any chest pressure or breathlessness before taking the Iodine though. So it surely must be a detox symptom related to the iodine. So if my test results come through all fine still then I guess I have to decide whether to push on ahead with some higher doses. Would be good to hear if the higher doses are faster at fixing up the chest pressure. I feel I can deal with the other detox symptoms but that one is just too scary.
