My husband would be distressed to hear that because he just started iodine!!! As with anything else a balance is required...all minerals are neccessary for the body to function, but when there is too much of one, things can go off track. I can't take Lugol's for some strange reason, not even on my skin (not even 1-drop)! I have found when I take it I get wierd headaches, feel wierd, tired and my teeth & jaw hurt. As soon as I stop it all goes away. I plan to try detoxified Iodine as I heard that if Lugol's does not help than sometimes detoxified can.
