Hi Grizz! Thanks so much for the links. There's loads of information there. I was worried about taking too much iodine. There's so much conflicting information on the subject. The Iodine I'm taking is the one supplied to those affected by Chernobyl - I figured that was strong. Clearly I could go even higher. I'll take a look at the group. Haven't been in yahoo groups in years... I half though they didn't exist anymore. Again... thanks!
