Midnight-
As you know I don't have a lot of experience with AVRT, but a bit back I realized that for me it is no longer about a particular food but about the misuse of food, and binging. For me it is about the "reason" I am doing it which is almost always emotionally driven.
I don't have any answers but I will put out there that for me the "binges" have lessoned in amount and intensity over time. They are still up (though less) then they used to be during times of extreme stress.
I plan on looking more into AVRT with that part in mind. Doing away with an individual food or food group for me is still eating disorder behavior....of the restrictive kind which is just as bad, and for me typically cycles back around. However if I could set it up as a behavior piece it is something I would be interested in adn could benefit from.
