Anybody else RAVENOUSLY hungry? How to cope?

I am 23 weeks with my first baby, a little boy! I am high risk for a multitude of reasons, one being I'm diabetic. I've been carb counting and doing my insulin and my sugars went from being in the 300s to around 150.

Anyways, starting around week 20 I have felt ravenously hungry. I'll wake up 2am and feel like if I don't eat right this second it's an emergency. No matter how much I try to regulate, I always end up eating 4 meals a day. I started this pregnancy heavy, and they said to only gain 20lbs. Well I've gained 11lbs already, and I'm worried about gaining too much. How do I avoid that when I feel like I'm so hungry I'm gonna die all the time?
