Just popping in to say that I can not drink the drink due to a preservative allergy. My first OB had me eat a big carb meal and have my blood drawn two hours later. My second OB had me eat a specific number of jelly beans (I think it coordinated to 50 grams of sugar) and then I had my blood drawn an hour later. The biggest thing for me is to eat a high protein meal or snack about two hours before I eat the jelly beans. Otherwise I am also very queasy and I will actually fail the test on the low side. So, don't fast for this test.
