my blood sugar the last 3 days have been in the 160 range. I am on 1000mg of metformin daily, watch my diet, and exercise up to 1hr to 1 1/2 hrs daily. My test usually run about 103-115. I have checked my blood for the last 3 days after exercise, and at least 3 hrs after eating, each time they are over 160. Nothing has changed in my daily routine. everything is done at certain times daily.Hope you can help. Thanks
