Thanks so much for posting this as it validates what I have been thinking is going on with me. Hypothesizing that my thyroid has been unable to fully utilize the Iodine I have been taking due to it's problems assimilating calcium properly. Since Iodine helps to calm hyperactivity, it makes sense that you might feel hyper without it. What does Dr. Flechas say about it, or have you had a chance to ask him?
