Completely agree with Trapper at this. Iodine is out of body within a couple of days. So not taking it for weeks /months still blaming it for ones problems is like attacking the postman for the invoice he might bring.
Twice in my life I have experienced heart palpitations en masse. First time when I was hypo thyroid 10 years back, next time when progesterone was low. //www.curezone.org/forums/fm.asp?i=2352796#i
Both times Iodine was needed; the latter (9 years after) / menopause problems; progesterone calmed it all down. It can start as low as in our 30`ies; the lack of progesterone (in that case thyroid hormones doesn't work)
Best of luck whatever you choose to do.
