Sounds like you just need to get back on the wagon. I don't think surgery is the answer. Too many of those people gain the weight back. Dr. John Berardi states that you only need to be 90% compliant with a diet regimen to get the maximum benefit. That's an encouraging though, right? This means you're allowed to have cheat meals within the week. Just make sure you stay around 90% compliance and you should be well on your way towards achieving your goal(s).
