Well, I have to say, if nothing else, iodine is giving me more energy. And what perfect timing! A few other things I have noticed:  1) I swear the groove between my eyes is softening, 2) my tongue is gaining papillae, and seems flatter and less scalloped around the edges, and 3) I have a tickle in my esophagus near the base of my thyroid.  Last week I felt the tickle lower or so it seemed, and it made me cough until I took some garlic.
