Hi Susy: Yay for coming off the insulin! You sound like you are doing a great job keep up the hard work
i was diagnosed after the 28wk polycose test, then following GTT test (both were high), the funny thing is my DH is a type1 diabetic so now were a diabetic household! Managed on diet alone until recently when they put me on metformin (just breakfast and dinner) as the insluin resistance was dropping further as buba is getting later into the pregnancy. My glucose readings are pretty spot on, i just get a bit sick of being on such a strict diet and the nutritionist has put me on 30g carbs per meal (equivilent to 2 slices sandwhich slice voguls bread).
My DH is on an insulin pump as he is a cyclist, but when he has a hypo he uses mentos mints (used to be jellybeans) there was a study out 2 years ago which showed that the mentos mints vs jellybeans got the glucose into the system faster and got the glucose levels back to norm quicker than the other lollies. So maybe you could try that?
I swim alot and i keep a little stash in a zip lock bag next to the pool with my water bottle, so if i feel it going low cause of the exercise i stop and pop some hehehe. Everyone gives you funny looks though 
God it's hard enough being pregnant without the GD as well so well done all you ladies....
