Diabetes, Type 2
"Have been on metformin for most of 7 years. I have not experienced any side effects as far as I can tell. It helps control my blood sugar. But the most effective control I have is diet. I was eating healthy and exercising regularly until about 2 years ago. Had my A1c down to 5.9. Got lazy and now it is in the 7&#039;s. Also have arthritis in knees and it is hard to exercise. I take 2500mg a day."
