Benefits of Iodine for Health

I have been using 12.5mg's of Iodine/iodide and selenium for 2 weeks now and it has been a Godsend up till now. After the 2 weeks were up I started having the same symptoms as before. Severe anxiety/fear, fatigue and really cold extremeties. I am convinced that I cannot be without a prescription now for Hypothyroidism, whether we use synthetic or non-synthetic. My symptoms cannot be stabilized without the help of western meds now. My TSH level were at 4.8, 3 months ago now. I will report back when I am on a prescrition med to let everyone know if there is a big difference. I see my PCP tomorrow.
