Metformin /Type 1

How do you know if you are on the right dose? Mine hasnt changed in years and have always struggled with weight. And insulin resistance, how do you know it is better unless you stop taking metformin?

In theory, the maximum dose (two 500mg tablets twice a day) should give you the maximum benefit if you don't have side effects. I agree stopping it and seeing if things change might tell you if it is working. Simon H
