I too, am on my first days of metformin. I started it on Satruday, only taking 500mg a day until next saturday when Im going to take the full 1000mg dose. So far, I've been going to the bathroom more than usual (nothing unbearable by any means) and i haven't really had any strong cravings. I think I have already lost weight too...the scale SAYS ive lost about 4lbs...but im going to choose to believe that my scale is crazy or off-track until that number goes down again

Anyway, did your doc tell you to change your diet? What are you doing about diet? I have been eating a balance of carbs to protein. Something I read about in the insulin resistance diet book.
Good luck!
