Three weeks into taking glucophage I've lost 13 pounds. All I can say is wow. In the last two years I've gained 40 pounds and up until now have not been able to drop any weight. So even though some people disagree on taking glucohphage for weight loss I'm impressed with it. It's helped me change my eating habits, lose weight, feel good, and I don't have endless heartburn all the time, yaa.
