I too am having revision surgery on 05/30 because I regained 200 lbs. yes, 200! It worked for me until it didn't and it seemed I gained weight no matter what or how little I ate so its time to do something different. I've had an endoscopy so we know what went wrong where with the surgery as a tool and I have had 14 years (12 as weight gaining) to examine my role in the failure of myself and my tool. I am determined not to make the same mistakes that I can control this time around. I am 53 and don't want to go into old age as a fat woman with a bad knee limited in how i live my life.
