I started about 4 weeks ago.... I started on 2 iodoral a day, one in the morning, one in the evening. I have slowly from there built up to 4 tabs daily like you, over 4 week period. I have found it quite a "ride" with quite a few symptoms coming through including pimples, emotional changes (up and down), Iodine mumps, and metalic taste in mouth. I take this all to mean I AM HEALING!!!!!!!!!!! All i can say is, maybe if you feel you are getting a reaction that is a bit too much for you, maybe build up slowly and start with 2 tabs a day till you feel you are able to increase. Good luck.
