For Type 2 Diabetes "Metformin (Glucophage generic) works very well without any side effects (maybe a small bit of diarrhea and gas - but that helps get rid of my constipation). I am NOT overweight. In great shape with running, playing tennis and golf, etc. Age 65. Never was overweight. Got diabetes from drinking way too much Coca Cola and eating too much sweets (donuts, cake, candies, etc.). Always burned off the sugar so never put on weight. Never knew sugar was a poison that affects metabolism. Started taking metformin (3 X 800 daily dosage two years ago). With diet changes, brought down my blood glucose level from 358 to 130, and A1C from 15.9 to 6.7. Not out of the woods yet, but huge improvement, and metformin is the only drug that works for me."

For Polycystic Ovary Syndrome "This medicine has definitely improved my quality of life. Within the first 2 weeks of starting metformin, I lost 8 pounds (where before I struggled to lose weight). Now I am in a healthy BMI for my height group. I experienced no nausea while taking this medicine (I took it in the middle of a meal). I did experience some intestinal side effects (gas/diarrhea) for the first week, and in the first week, I increased my dose."

For Type 2 Diabetes "My husband and I are both on this medicine. He takes 1000 mg morning and evening. I take the max at 850 mg each meal. We have to keep a packet of desiccant in the bottle to absorb the horrible fishy smell. We both have the side effect, even years later, of bloating, gas, and flatulence. We call this pill our 'gas' medication. But it lowers our blood sugar with few other side effects. If we're out, we take it on our return home if possible to prevent inflicting our flatulence on others."
