Good luck! My friend and I were joking the other day that we wish we had overactive thyroids so we could get some kind of magic pills. I know we don't really want it.
I hope you will find the answers and be able to maintain a healthy weight without any medication. I am really afraid of taking medication - I will take it if absolutely necessary, but I don't like to for some reason. Anyway, I hope our resident nutritionist Cherish will be able to give you some answers.
