Thanks for your update. Do you have or have had any mercury fillings in your mouth? I did years ago. They all have been removed. For whatever it is worth, I find when I take high doses of iodine, 2 grams or more, I really stir up the mercury left in my body which really seems to be affecting my short term memory. I recently started chelating strictly following the cutler protocol. I have had to decrease my Iodine to around 50mg/day though. Chelating mercury and taking Iodine really stresses my adrenals. I seem to do much better on Iodine off round tough.
