Wow you sound almost identical to me and I am going through the same process. I have moved from the kelp supplement to Lugol's though and tried starting twice before with horrendous side effects. I am now on my third attempt on 1.5mg of Lugol's. So far so good, fingers crossed I can tolerate it. I too am high in metals and battle candida and react badly to things other people have great results with. And peri-menopausal too! My neck got a little swollen and had pressure on the windpipe for a few days, This came and went about 4 times all up but this is all normal apparently as the thyroid swells to try get more iodine. Make sure you are taking all the accompanying supplements - these are really helping me. And pulse-dose if it gets too much. I am having to do this too.
