I'm sure thus has been asked before. Im in need of a pick me up and wondered if there are any positive stories re carbimazole and weight gain. I was diagnosed with graves disease 5 weeks ago, and I've since then started piling on the weight. If I have a strict diet and exexercise program is it possible to maintain my weight? I'm currently overweight and all in info I've read re carbimazole has put me off taken it to the extent I'm very nearly going to stop.
