I think it's very introspective that you are asking yourself that question! I had a gastric bypass and I regained 55 pounds from the 100 I lost. I stopped my support group meetings, and stopped using many of the tools I learned before I had surgery. For me, stopping the carb intake is huge. Eating carbs I am constantly hungry. I went back to see the weight management people, I am seeing a dietician again, and I started Ozempic for appetite suppression as well as treatment for diabetes. Don't despair, you have sooo many options available to you. I think if you can get the carbs under control, you will see you still have the tool of the RNY available to you! You've just learned to eat around it.
Much luck to you!
