I am diabetic for about five to six years with insulin and prescription. however, after having a scare with my sugar being so high I gave up sweets, bread, carbs, and starting walking for 30 minutes. for the past week, my sugar has been what I consider low 75 or 85 fasting in the morning. after meals two hours, 110 I am not eating much since I am trying to take care of myself. should I be worried. tks.
