I have the same problem! I've found that next to all my food entries, i've written down that i was just bored :/
I usually work nights, and by the time i get home at 1045pm, the entire household is sleeping, my friends are sleeping, the dog is sleeping lol so there's really not much left to do but watch tv until i get sleepy and munch munch munch.
Unlike you, mine were always unhealthy choices! So first step for me was making them healthier lol next will be to cut them out, because I'm definitely not hungry, just lonely and bored.
Dragon's article was actually comforting in a way lol hope you read it too!
