I am right there with you. I have not been hungry yet. I just want junk food. And I do a really bad thing. I watch the food channel all the time :| Why do I do this to myself? I am absolutely 100% committed to losing weight and getting healthy. However, I am a food addict and I am nervous my old habits will creep up, maybe not in 6 months or a year but maybe 2 years from now or 5 years from now. It is scary, and in order to combat this, I think we need to really work on why we crave food and what the draw is.
In my classes I was required to take to get the surgery, they often said we will be getting bariatric surgery, not brain surgery and we need to be able to change the old us and our old way of life to be successful in the long run.
I think what you suggested is really smart. Just finding something else to do or going out to exercise. Do you have any sleeve or WLS support groups around you? Sometimes just being around people with the same struggles, keeps you in check. Someone once suggested keeping a thoughts journal, and entering in why you are hungry, what you want to eat, what was the trigger and things like that so you can in the future stay away from the triggers and understand why you crave.
I know we can triumph! Good luck =)
