Hi, your doctor is right in that it will probably help you lose weight (I read somewhere that it's sometimes prescribed to overweight people to help them lose weight, shame I didn't get it before I became diabetic!).
Since starting on Metformin, my appetite has reduced as a result, and I've slowly lost weight (just over a stone so far) with no effort from me at all. Even though I am getting a lot of the side effects (still!) from Metformin, I'm reluctant to ask to change medication, as I like the fact it's helping me lose weight - I also find I don't crave a lot of the high sugar foods that caused me to put on weight in the first place :thumbup: Even if you feel you don't need it to control your diabetes, staying on it will help you lose weight, and that might in turn help you reach a place where your doctor will decide you are ready to start coming off the Seroxat .
Definitely discuss it with your doctor though, they should be happy to explain why they think you need to take metformin.
