Apparently in some cases too much Iodine can make thyroid issues worse (I read about why this happens in a book by Dr. Barry Peatfield, but that was a year ago so can’t remember enough to explain it). Again it seems balance is what is needed: Too little Iodine = thyroid problems; too much iodine = thyroid problems. My doctor stopped the Iodine and put me on thyroid supplementation. I got a lot better, almost normal temperatures (though my heart rate stays low no matter what) and was fine until I started my very restricted diet. I may need to look into supplementing selenium though (seem to remember Dr. Peatfield mentioning that too).
Somebody in the forum had previously posted this link to a video series about iodine, selenium, and the thyroid. I found it educational:
