Is there something that's not related to food that would be a treat for you and help you with your "relief" nights? A group of friends to get together with? It's hard for me to suggest things, because only you know your schedule / abilities. For instance, if I needed a "get away" night, my first choice would be to go to a friends' place and just be with someone and take my mind away from food. It's hard, though, since everything revolves around food. I go somewhere, and the first question is "can I get you something to eat?". I know they're trying to welcome me, but it's funny how we depend on food to do those things.
I find my temptation is greatest at night, a combination of loneliness and boredom for me, so I've found a bedtime routine (actually starts well before bedtime) that makes it harder for me to be tempted. It's not the easiest thing to eat chips while soaking in a tub full of hot water and bubblebath. I'm sure it can be done, and has been done, but it's harder.
Anyhow, that's my thought. Instead of trying to take something away from yourself (food), replace it with something else (friends, bath, etc). Only you know your time / money restraints, but hopefully something will come to mind.
