Ask for doctor for diabetes education or do some research online and look for glycemic index and glycemic load. Learning to eat well and avoid sweets can help you feel a lot better and keep your blood glucose more stable. Also eating a little something every couple of hours. Now, I do NOT mean a meal that often but maybe 6 almonds OR 1/8 cup of sunflower seeds OR a handful of grapes OR a couple slices of lunch meat OR a boiled egg. Also everyone is different and you need to find out what affects YOU and what works for YOU.
