I am post op 4 years 8 months. I still eat Protein first, Fluid intake etc. however I still get sick if I even remotely try to eat the foods I'm not supposed to.
I was 280 pounds post surgery and am now 155. In my ideal world I was happy at 145, but am at a healthy weight for being (42 this month) and almost 5'8".
Keep strong, journal daily activities etc and when you have the urge to do something you shouldn't, walk away from it and occupy your mind with something else and the feeling will pass.
Good luck!!
