Hope this works. I’m new at this chat stuff. Anyway, I’ve been ‘normal’ for almost three years after RAI. Initially following RAI, my hormone levels took a nose dive, but never fell out of normal range. They slowly returned to mid-normal range and stayed there for about a year. Now I’m getting very close to being hypo and should start replacement in a couple of months. It has been a long wait. Not exactly stable, but probably as close as I’ll ever get.
