Sounds like Iodine normalises hormones but can take a few months to do so. It caused my periods to stop for 2 1/2 months, and I was having hot flashes and night sweats as well. That was on 12.5mg of Iodine so I had to drop right back and start at only 750mcg per day and am working my way up. Am currently on 3.1mg per day by adding one drop per week. The hot flashes have stopped and my periods have returned so perhaps that's what you need to do too - start small.
