You might have better luck getting an answer on the Iodine Supplementation and Support forum. It seems to be more active.
I know it's hard with adrenal involvement. I'm struggling with it, too. A few things that really helped me in the short-term: B12 injections, magnesium, high doses of ascorbic acid, and major diet cleanup. Also you might try a different form of iodine, such as Lugol's, and make sure you are taking the companion supplements.
I've been taking Lugol's for a little over two weeks now, slowly working my way up. I haven't noticed it affecting my adrenals.
