Any addiction's going to screw up your life - rather than hoping for an exercise addition (albeit one I've wished for in my previous life), I'd suggest to anyone dealing with WLS to get a good therapist and see them, at least monthly, for 2 years post op, if not longer. We're far better off seeing a therapist when we're entirely psychologically healthy and addiction free (excepting food, of course) and staying that way rather than waiting until we need it. That said, the likelihood of addiction switching from food to sex, drugs, alcohol, gambling, exercise, etc is no greater (and no less) than the likelihood of anyone else quitting another addiction swapping to another one. There's a reason for all of that coffee and those buckets of hard candies at AA, NA, etc meetings - folks just swap to something more socially acceptable. I'll agree I'd rather my own child was addicted to coffee than nicotine or narcotics, but I do wish 12-step programs did a better job writ large (I get that this is a HUGELY oversimplified generalization) of helping folks do more than just 'kick the ____ habit' and focussed on building a whole self in recovery. But that's just my 2 cents. In short - yes, you've got a higher risk than someone without other addictions, and a higher risk than if you stayed in your food addiction, but nothing some dedicated, honest, and vulnerable work with a good therapist can't help you through. Good luck!
