Just wanted to post a quick note about my success with taking metformin. (I'm not diabetic, nor do I have PCOS, just taking for weight loss. So far I've lost 6 pounds in 8 days. My weight is staying off. I've lost my craving for something sweet after each meal. It feels really good to be able to maintain a weight loss. I've cut out bread, except for the ocassional slice of whole wheat, along with pasta, potatoes etc. I plan to continue taking metformin. The ill effects I initally experienced have pretty much subsided. Woohoo.
