You may need to supplement to regulate your blood sugar levels. There have been extensive clinical studies on several food supplements (not just vitamins) that give you easily absorbable nutrition without the blood sugar spikes. There is a well-regarded study on metabolic syndrome and diabetes control. You might also find that properly nourishing your body at the cellular level (vs. just what you consume that isn't absorbed) will reduce the cravings.
You are craving carbs because your body is starving for something - but you're feeding it the wrong thing. Keep some whole almonds around for a snack - I keep some in my purse for when I'm out and about and likely to just grab something that's not good for me. It's a good protein source and it's crunchy, which helps. A friend found that was the only thing that kept her nausea at bay while she was pregnant.
I think you are waiting too long to eat. You say you are too distracted to remember, and that's not a good thing. Please put 5 meals into your daily routine - 5 small, balanced meals or snacks. A handful (about 15) almonds is a snack - and it's a lot of protein. Keep some brown rice or especially quinoa cooked up in the fridge that you can just grab a small bowlful - it feels like carbs but it's got protein too.
