When you get the urge to snack (my weak point is when I walk in the house after work -- I'm hungry and supper is about 30 minutes away) eat something that is good for you but not overly "tasty".

I eat a hard-boiled egg or two, or I ignore the hunger and get supper going if the egg looks really unappetizing (honestly, I like hard boiled eggs, but at that point what I really want is some [okay, a LOT] of salted nuts, or a big chunk of brie, or some lc candy...).

The idea is to satisfy real hunger, and recognize habit and not indulge -- that is, if you are actually hungry, the egg will do; if you're not hungry and just want some comfort food, then the egg doesn't appeal and you know to ignore the urge....
