If you haven't already done so, make an appt with a dietician ASAP so she can put you on an appropriate diet and talk you through what you need to do. Your OB should be able to refer you. I had GD 2 years ago when I was pregnant with DD, and controlled it very successfully with diet. It took some perserverance to learn what I could and couldn't eat, and when, but you can do it! By the end of the pregnancy, it was pretty much second nature (except when I couldn't have any cake at my own baby shower! That was still tough!). The trick with GD is that, unlike a regular diabetes diet, you have to manage sugars and carbs but NOT cut calories. This generally means more protein and fat (which was very, very strange for me, since I'm usually a low-fat vegetarian!). I, literally, had bacon and eggs for breakfast almost every day. For days when I was in a rush to get to work, I'd hard-boil several eggs at a time in the evening, then eat off of those for a couple of days. Read cereal labels carefully--there are some that you can eat, but you need to avoid any with a lot of added sugar (it's nearly impossible to find ones with NO added sugar--trust me, I tried! Even Kashi let me down!). You can buy plain oatmeal, then tightly control what sweetener you add. No-sugar-added peanut butter on a whole-wheat English muffin also works. Also, since you have to eat every 3 hours, I actually ate a smaller breakfast, then would have my required snack around 10am. GL with everything! You can do it! And like the previous poster said, it's SUPER important for the health of you and your baby!
