Iodine deficiency affects your entire body, brain, thyroid, & hormones. I suggest you start with 1 drop of LugolsIodine with co-supplements daily, then titrate up to 50mg of Iodoral tablets over the course of 6 months.
I also suggest that you go on a Paleo Diet. You are robbing your body of vital nutrition. Also get that thermometer & chart your morning body temp every day. You should be close to 98.6 degrees.
