I was also on glucophage nd was always starving. Was never nauseious, but hungry, hungry hungry. eat whole grain pastas and breads and it'll fill you up. btw, I was on gluco my entire pregnancy (if you read my pregnancy posts on my blog) and it saved my baby's life. I'd defintely tell you to stay on it for the first trimester as it cuts miscarriage risk. I didnt know you had pcos!
