How to curve night time munchies?

I cook double veggies with supper so that if I get hungry later, I can eat that instead of being tempted to start looting through the cupboards. Now, let's be realistic here. Do I still want the junk? Yes. But do I eat the junk? Nope. It's not an easy decision to make, and I definitely wrestle with my own brain from time to time, but losing weight and being healthy is worth it to me!
