Great advice above!!
1) Don't restrict - because if we don't restrict, we don't binge! "I can have whatever I want! While I decide, I'm going to make myself a cup of tea and think about it for 10 minutes. If I still want it, I will buy myself a super awesome excellent quality treat!!"
2) Leave the place/room - go for a walk, call a friend! usually I binge because of a trigger, a kind of anxiety or stress - that's the problem, not the binge. Sometimes I find a better way to deal with it,
3) Make it fancy. Sometimes, I say "screw it" and decide I am definitely going to use food to soothe my issues. Instead of a never-ending snack binge of doom, I plan a big feast with distinctive courses - appetizer, main, dessert, a nice drink, pretty plating... Buy excellent quality foods - no box cookies, get a pastry; No crackers - buy some fresh bread. If you catch yourself with the desire to binge - go and treat yourself to a restaurant! A real treat and a guaranteed control of portions! (while being greater than a dieters portion, it's much less than a binge protion.) Plus, getting out of the house really helps!!!
As for damage control:
Forgive yourself and enjoy
This has helped me get real with my binges, those horrible hopeless days.
