I feel it's probably best to start acting (in your head and with what you eat) ahead of time. You know the old quote...walk like a duck, act like a duck.....you might just be a duck. Well we need to start to change our relationship with food now....today...because the surgery can only do so much for you....when the rubber meets the road we are gonna have to make permanant changes. So you have plenty of time to practice and get good at it.
