After a fasting BS test I'd just been diagnosed. My doctor told me to try to manage it with diet, so the second thing I did (after getting a meter and strips) was to drop past the store and get myself something suitable to eat (I hadn't eat yet, remember?). I was walking in to school carrying a bag of groceries and the first person I see asks if I'd been shopping, so I felt I had to explain why I was carrying food.
I explained about the diagnosis and the first thing she said was "well now you'll have to stop drinking Coke". I drink Coke Zero you idiot!!!!!!
