What do you suggest if i have been taking metformin, for diabetes, for two years.i soon started to feel sickly now and again.?

Diabetic Medication: My number one recommendation for all of my Diabetic patients is to understand their disease, to test their Blood sugar regularly and to keep a log, and to see a specialist (Endocrinologist) for proper control. Sometimes one medication may work for a while, but often the disease progresses, and other medications, and eventually Insulin must be added to the treatment regimen.
