I keep reading that Metformin is not a weight loss drug but lowers blood sugar some. My doctor said at the beginning that it does not do much, but I think it is effective for me. I can overdo at dinner and have the number back to normal in the morning. But not every day. I am wondering if anyone has been taught about the normal ups and down of blood sugar and how diabetes makes the blood spike high and then drop low two hours later and then go back up again in a wave pattern if normal, and in peaks with diabetes. When I saw that chart, I knew better who to eat and when to eat to control the ups and downs. Metformin helps the number to go down over night but not as much in the day, I have discovered. At first two Metformin pills made my stomach hurt a little over night, but then I got used to it but was very hungry in the morning. But I have always had a sensitive stomach due to stress. Basically, changing lifestyle is the way to go for better health. Insulin is for serious cases, and I never had to go that route because my diabetes was discovered early on. I hope this helps the new people who haven't been taught much about their disease. There is always more to learn. Dorisena
