Not to butt in here, but the question caught my attention b/c everytime I try to do iodine, I go to great depths of depression. I did the salt, niacin and selenium along with it. I can't figure out what I'm doing wrong in regards to the iodine. I tried Lugol's then detoxified(whoahh!) and finally just some kelp. But everytime my period gets wonky, I gain weight, it feels like my tendons are being "played" (like an instrument). I also get the sensation that biting sensation, or like things are being pricked out of my muscles and bones. I assume this means I need it. Any ideas what could be going on? Oh yeah, I did have mercury removed(5) about 2 yrs ago due to overgrowth of candida(plus other things). This helped me tremendously in gaining some health overall. But I know I have such a long way to go.
