My husband has two cousin's who are brittle diabetics. Both of them got pumps when they were adults and say it worked wonders. One was constantly having to regulate her blood sugars by drinking lemonade or straight coke 'cuz it'd drop so fast. The other one was also married to a brittle diabetic, who'd get so out of wack she'd have episodes -- I think of Julia Roberts in that one movie... name escapes me -- anyway she once BIT a grocery clerk.
