Like "Use glucose tablets. They have fewer calories and work faster than soda. Then eat something small with some protein. I eat string cheese. That little bit of fat and protein stabilizes me for a lot longer. Regarding the workout, if your blood sugar is below 100 when you are getting started, eat a protein bar (with 15g of carbs) and don't take any insulin. If you are doing 20-30 minutes of rigorous activity, you should be fine. Check your blood sugar when your done."
