You have lots of room to go up on your metformin before heading to
insulin, so discuss this with your doctor. The usual dose of metformin, assuming your kidney
and heart function are fine, is 1000 mg twice daily. It may also help with your weight loss. Continue with the dietary changes to lose some weight. You definitely need medication in the evenings if your morning blood sugars are the highest, so perhaps this second dose of metformin can first be added at night to help.
