What a wonderful post! I would want you to receive an "R" except for one little thing...
...iodine is not a drug!!!!
It is a halogen that is a nutrient that the body needs - just like the air we breathe and the water we drink.
It's something the body must have and that most are deficient in!
I know what you're saying...I too have had heart issues, (palpitations and an arrythmia). Iodine supplementation has cured it - and I've not had this previous 10+ year problem for over a year and a half now.
