I believe that all of us who have had RNY have some sort of food addiction. I can say that I have succeeded in this process because I knew that I really NEEDED to succeed. For me it was matter of daily back pain and the need for back surgery that pushed me to RNY. With the pain, my life had changed so drastically and I became very depressed and isolated myself from my family and friends. I needed to lose the weight to fix my back and get back to living. I agree with oldoneyoungagain in that dont do this if you are mot truly ready or you will end up resentful. It is a total life change and one that you must be committed to. I am 5 months post op and it is still hard to pass up food at times and I have moments when I think, "oh I dont care how much sugar it has. I want it!" When you are able to walk away and not eat what you would really like to eat, it is very empowering. My addiction to food will be lifelong im sure, but my will to be successful in this process will overcome that addiction!
Best of luck to you on your journey!
