Weight gain with DS?

I have heard of people with the DS regaining up to 50 or 60 lbs, but have never heard of someone regaining all their weight with the DS.  The average expected bounce-back is 15% of EWL, if I recall correctly.
 
Like everyone said here, you can beat any surgery if you try hard enough! Surgery is just a jump start to changing habits and re-learning how to eat. Take advantage of it and use it as an opportunity to develop new habits.

Best wishes on your upcoming surgery!
