Rick, You know you need to get the mercury out that goes without saying. Before you start back on Lugols try detoxing some of the metals, with IP-6 2 grams+/day, R-Lipoic Acid 150mg X 3 day and Vit C 6-10 grams per day spread out over the day to assist in flushing the metals through the kidneys and bowels.
After a month try starting 1 drop of Lugols per day. Your going to get detox no doubt about it. I would just try to prepare myself before hand. I worked up to 1.2 grams a day, and I had detox like a bad boy in the beginning. Now if I feel something coming on I'll drop a gram, with no problems other than it clears up what was beginning to come on. Point being you will get over the detox, depends on how much your willing to handle.
