How is your treatment now if you don't mind my asking?? Are you still doing the Metformin or did you switch to insulin? I never tolerated Metformin well, it gave me low blood sugar throughout the day and tortured my GI tract even at a low dose... When I had a glucose tolerance test in my late 20s I got a response like yours, but the doctor never said anything about it. So I tested myself at home with a glucose meter and a measured carb meal--still spiked high and crashed. I've always had issues regulating that post meal reaction unless I leave carbs out of it entirely. I'm really curious to see how my numbers do long term, but I will be sure to never consider myself "cured"! Diabetes is a life long illness even if you have nice numbers sometimes.
