I am a Type 1 diabetic and even my blood sugars in the morning are high. To bring it down I did this exercise, checked for blood sugars between 2 a.m and 4 a.m it was low and then in the morning it rises. Added to this there are hormones that contribute to the morning sugars. The best way to treat is eat a slow acting fiber food when you go to bed, if your sugars are between 110 mg - 150 mg 2 hours after dinner. Do a strenuous exercise in the evening before your night time medicines. This will definitely bring down your dawn sugars.
