I've had trouble with that kind of thing too. Sugar or very high glycemic foods seem to always drive my hunger even higher until I have had way too much. Then there's the aspect of how habit forming just munching at night in front of the TV is to me. I have a lot better luck dieting if I switch my sugars to pre ride, so I eat some and leave the house and the source before I get out of control. At night I go for dry popped organic popcorn or carrots and sour cream-based dip to satisfy the munch craving.

Those are just strategies I use to start getting off the habit. I do much better when I take those strategies and use them to move into waking very early and going to bed very early just to prevent the late-night snacking. When you make it into a habit you actually get a dopamine hit from it along with the sugar. Sometimes it's harder to break the dopamine habit than the sugar one.
