Does everyone have binge eating nights?

I just wanted to know if my "binge" nights are not totally out of control. I am in really good shape and eat a healthy diet but sometimes, like the woman i am, i have those nights were i just want to munch on everything. I try really hard to "snack" on good things but I can't always help it. I'll eat tons of crackers or cereal or whatever. I feel like i go overboard. It may not sound that bad but I feel so horrible afterwards; like I've completely ruined all the confidence i have in my healthy diet. In general i'm really good at controling what i eat, but these nights of binging, which arnt all that often (like once a month), normal?
