Lu,
Please keep us updated. I am currently in the same boat... My first year after banding I was quite successful. I hit a plateau - which I figured was to be expected... but this past year, I have been putting weight back on - I know stress management is something I need to work on, and it certainly wouldnt hurt me to walk a little longer or farther either.
But I do find it discouraging... In someways I am embarrassed to go back to my doctor because I feel like a failure.. But in my heart and mind, if I do nothing, than I am destine to fail.. Best of luck to us both!
