I hear you mama annie. I had two failed WLS's for complicated reasons and still had to figure out how to deal with my weight. I truly believe that most of us get to some point where we realize the only way to stay on top is to keep looking at those food choices. The surgery is only one tool that can help. Also, the banding is often considered low success for reasons such as the experience you've had. You can still make this work for you I' sure. Do you still feel the same restrictions in terms of how much you can eat, or the textures for instance that you felt in the beginning? Has your pouch stretched? Have you changed how you eat since before the surgery, or since you lost the 90 pounds after?
I'd have to have a lot more information about your current way of eating to venture any opinion about what the problem areas may be.
