I haven't been banded yet, but I know all about the sweet cravings. I will say that I have been amazed at how quickly I lost the sweet cravings when I strictly followed a South Beach plan. Took about 5 days, and then magically, I could look at candy or Cookies and think, nahhh, what else do I have? I just wasn't interested in them! Amazing!
Of course, now I am a meat addict.
So, good luck to you!
