i have them years after high dose Iodine if you read my older posts.
trapper was wrong, you need to start small with Iodine and slowly build your metabolism. his heart attack came from him taking grams of iodine, and then smaller high doses afterwards.
you wouldn't have went bald if you took a little Iodine to speed up your hypothyroid.
your heart will not slow down now until your metabolism catches up with your thyroid, it can take years in my experience.
just hope and pray you don't get a heart attack during the wait, look for heart supplements like hawthorn berry, taurine, magnesium, carnitine, ubiquinol, etc...
