Hi Suzie, I have been surfing the web in hopes of finding out what is going on with me and I think your situation has helped me understand. I started taking a thyroid supplement (it had Iodine in it) about 6 months ago, at first my results were amazing, I gave this product a 5 star review, I looked back at that review and I was over the moon, so much energy, and other issues were being addressed, I was IN LOVE. Then about 2 months ago, I hit a brick wall, suddenly my sinuses were killing me, I've never had such a bout with them, but, they were draining, and drain they did, but in the end, my energy level has plummeted. I drag around feeling like I am the wife of Dracula, zero energy. Finally, this week, I began to take a look at what was causing my continued low energy, before that, I had in my head that it was related to my overloaded immune system fighting the allergies and sinus issues. Two days ago, I stopped using the supplement that has the iodine, and I am feeling better. I think I will go along with no added iodine, this supplement may have overloaded me. Anyway, I like what you wrote, it helps me to see what I think happened to me.
