No muscle pain or fatigue before starting. I was fine day one, just a little warm. By day two I had terrible pain in my legs and back and was very fatigued. I had on and off feelings of heat also. I didn't take the Lugol's day three and I still had the pain. I took it day four and the pain and fatigue increased, I was in bed most of the day. Today is day 5 and I have the pain and fatigue still. I did the salt this morning. I'm using celtic Sea Salt . I'm only taking one drop of 2%, this detox seems a little extreme. I have had candida for a long time and have a lot of mercury fillings, but it still seems like its too much. I'm off to do more of the salt. Any other suggestions?
