@rrobinson2,
You're welcome! With a lowered metabolism, it is very, very easy to put on weight. Obviously you've started some good habits if your weight is remaining constant, so keep up the good work!
It's been 3 months since you started taking supplemental thyroid hormone, but how long ago did they up the dosage? Once they find the correct dosage, it should only take a month or two for your metabolism to be back to normal.
