Hey 10again,
Hope you can find a way to stop going down that chips aisle...

Maybe just pay attention to the thoughts you're having when you head that way... I'm sure they must not be about losing 5 pounds, but what are they about? Are they, "I've worked hard and I deserve this"? Are they, "Oh, heck with it, I'm going to have some fun"? Or "This weight loss idea won't work--nothing matters anyway"? It might help to see what's going on.
When you're ready to lose, you'll be better able to stay away from that aisle, the sodas, etc. After all, I assume no one is dragging you down there and taping the bag of chips to your hand and then later putting the chips into your mouth...?
You have to find a way! Good luck!
Jay
