I too had a very similar eaction as well and I have a thought on it, I have been thinking alot about why it affects some more than others but since its not the Iodine thats causing it ( I'm going by all the info I have read) but some sort of detox like heavy metals ect, can viruses we have in our bodies also cause a bad reaction in us due to the Iodine killing them off? I say this because I have just found out that I have Barmah Forest Virus and I had it when I started Iodine so maybe thats why some people have a bad reaction they think is the iodine but is maybe from the reaction to viruses in the body, Its just a thought..
