My endocrinologist just prescribed me propanol and I was wondering if anyone who's been on it can tell how it went? I have crippling anxiety and my heart rate jumps astronomically if I just stand up. I'm also starting methimazole again after being off it for 6 months. I really don't want to gain anymore weight as I'm getting fitted for my wedding dress this week, last time I took methimezole I gained 35 lbs and haven't lost a cent since being off it. Is there anyone that can tell me a diet and/or workout regime that helped them stay the same weight at least?
