Not trying to one-up our friend up there, but I would just compare how fighting any addiction will take its own toll for a bit. In one year after quitting drinking, I went up to 200 from around 175, the heaviest I have ever been. It took a bit, but I am finally down to a healthy 185.
I think what I am meaning to say is that if you are battling an addiction of any kind, eating too much should be the least of your concerns. No cigs? No booze? That gallon of ice cream is OK to eat in a single sitting then. Learning to moderate food can come much later.
Every so often you just have to fill yourself up with pizza till reality stops hurting. Pies can't cure you but the food coma certainly helps blunt the pain for a few hours.
The other day I had a flash of german nostalgia craving and bought a frozen Benjamin Blümchen Torte. Still as good as I remembered but after two thirds I started to regret my decision
