tell the dr what side effects the metformin does to you. I had to do that with it and went on glipizide! wow what a difference. I recently have lost 25 lbs and no longer have to take my meds. it is the food you eat. I have cut out all pasta, potatoes, etc. You are doing great losing the weight but you really have to watch what you eat. I do get my cravings and I was a carb junkie! you can do this. ask about a different medication.
