new to metformin, what can I expect?

jamie007

So m Dr. talked me into trying some Metformin mainly because I am pre-diabetic and am not able to lose any weight. My fastings range anywhere from 93 to 114. After meals I am usually under 145 to 140-ish, sometimes depends on what I eat i've climbed to 169 two hours after a meal.

She thinks that if I can get my numbers under steady control that that will help me to lose this weight and feel better. I am to take 500 mgs of Metformin for one month then retest cholesterol and all that stuff because I am exercising and eating better now too but still with no weight loss.

So can someone tell me what Metformin will do? How does it help me lose weight? She said once I lose the weight (20 to 30 pounds) that we can try to wean off the Metformin.
So what can I expect? any input please!
