I too have been on Lugol's for five months. I am disappointed that I have not had more success, although I have some big "gets." I think it is a matter of the glass being half full or half empty. The truth is that my glass was pretty empty when I started, and I had several diagnosed diseases, none of which was hypothyroid, but my consistently low body temperature was a big clue to that.
I guess my problems didn't come in five months, or even five years, so I am looking at how far I have come, not how far I have to go. I do feel, that Iodine is cheap at the price, considering how far I've come!
