No matter what, you HAVE to eat breakfast. Studies has shown that dieters who eat breakfast lost more weight, and quicker, than dieters who don't. Even if it's just a glass of milk, an apple, a bowl a cereal, it doesn't matter, eat it. I have the same problem you do, but I still eat breakfast, and, although I'm hungry at lunch, I only bring enough, or by enough to make myself not hungry, not full. Good luck!
