Very interesting... I'm gonna try potassium.
Maybe I'm in denial, but I still don't think being cold has much to do with my thyroid. I still think it's a fluke thing that happened under extreme circumstances. Since adding the extra KI, in 2 days, the big butterfly bubble in my throat shrunk.
It's now 3 and 1/8th" on the left and 3" on the right and and 3" across. It went down about 1/2" - and without synthroid TYVM!
