I am on Metformin and it seems to stop cravings I would have had with seroquel.
I can also feel it taking the sugar out of my liver before it can be turned into fat.
I think it helps prevent any new weight gain from any APs or Anti depressant.
But I am also on a low carb - high protein diet with Nutri-system in combination with the Metformin and I have lost almost 20lbs.
