Good to know it doesnt contain the other halogens. God..I cant imagine what kind of Iodine detox id be having if it did..I was on the stuff for so long. But yes..I still sometimes dont feel like its all out, and Ive been off it since age 18. The initial detox when I stopped it cold turkey was by far the worst pain Ive ever been through in my entire life. Including this horrific infection on my face Im battling now. During zoloft withdrawls, I truly, without a doubt in my mind thought I WAS going to die.
