Synthroid and Iodine

I had my thyroid removed 8 months ago and take 100 mcg of synthroid per day. Had I found this forum last year I can almost bet I would not have had the surgery. I had several small nodules that were said to have been borderline cancer. Of course at the time, all the doctors, hospital surgeons and radiologists said you have no choice..! aarrrgghh
Anyway, my question is, does anyone out there have no thyroid and have found that they need less and less thyroid medication after successful use of iodine.?? I have gained about 15 pounds the past 8 months and see it going up and up.. :-( Tweet
