God, your post brings back memories for me. That is exactly how I felt when I first tried iodine. I ramped and backed off so many times. Now I take it with ease. It does sound like bromine. You would be surprised at all the ways you get bromine into your system. Bread I think was my worst enemy. I almost never eat it anymore. New office furniture, carpet, clothes. It is endless. Keep trying and make sure you take the co-sups. They are important. There is so much more. Don't get discouraged. I am sure others will chime in with their experiences.
