Hi jakatak, with an overnight fasting glucose score like that I would certainly be insisting on a 3- 5 hour glucose tolerance test or as aussiemom mentioned grab a blood glucose monitor and test your self.... just for a quick test I would try, eat a very high carb meal, top it off with something like jelly beans, icecream and wash it down with some soft drink and then test 1 hour after, 2 hours after, and also wait to see in [approx 1 hours time] if the pn symptoms flare up or not, this is exactly what would happen to me if i had something sweet.
good luck mate
