Measure
Metformin
Metformin 2000 mg per day Metformin (glucophage): The strength of each tablet will be 500 mg. Participants will build up to a daily dose over four weeks by taking one tablet per day for 7 days, one tablet twice daily for 7 days, one tablet in morning and 2 tablets at night for 7 days, and then 2 tablets in the morning and 2 tablets at night, daily throughout the remainder of the study treatment period.
Oral Placebo
A central pharmacy will compound a placebo to match the metformin tablets. The placebo product will contain the following components: * Micosolle™, silica based excipient * Silicified Micro Crystalline Cellulose, National Formulary * Safflower Oil, United States Pharmacopeia * K-30 Povidone Powder * Magnesium Stearate, National Formulary (Vegetable source) * Fumed Silica, National Formulary oral placebo
