What should a hypoglycemic put in her purse to snack on to make sure she doesn't feel badly?

Candy. Chewing gum, sugar in a bag. I find that liquid is the faster way to treat hypoglycemia. For example oj, coke. I have a teammate carry a bag/smallbowl of sugar in his sport bag, whenver he looked hypoglycemia we'll get water and mix the sugar and he will drink it.
