Oh man, I hate to tell you this, but since my RAI (5 months now) I have gained 30 pounds. It takes a looooooong time to get those levels right, so you may gain a few more. I am having a very hard time with the weight issue. The problem is my metabolism has pretty much slowed to snails pace, and I just didn't have the energy for any knd of physical activity for about 3 months straight. Not cool, since it is now swimsuit season, and I want to put that on about as bad as I want a hole in my head. The good news is I know it will come off......someday. Most people will need to have their meds adjusted at least once. Then you need to wait 2 months for the levels to become stable, and then you may or may not need to have them adjusted again, then wait 2 months, then blood test again......and so on until you find the right dose, by then you will probably have gained some weight. Hang in there, we do what we need to do. STUPID CANCER!!!!! Take care, Skylog
