If only we could all live that dream. I would suggest using a
log book, you can get one from your doc or
free from some meter companies. Write down your blood sugar before your meals, carbs you ate, if that is how you give yourself insulin, and your dosage. A carb is not a carb, and they are not all going to affect you the same. Also maybe the activity you had the day before, etc. If my son plays basketball the night before it affects him all the way in to the next day.
