Dear sir i can understand your concern. I am sorry to hear you have been having difficulties getting your blood sugar in the normal range now. I am very happy you are this conscientious because having a well controlled blood sugar is very important in preventing the onset of diabetic complications. In my opinion you are getting episodes of hypo,which might be due to medication what you are on. Metformin is a very good medication for diabetes and it is a first line medication,very rarely it causes hypoglycemia. i suggest you to reduce the medication too half dose and meet your doc continue your diet and exercise as usually.
