My son is 13 and been diagnosed since he was 4. Every day, every hour is different for his
blood sugar. I am a little disappointed your doctor has indicated everything should be regular by now. 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.
