I,m not sure how much weight i will loose, but I gave myself two years to reach my goal. My surgery for the band was in jan 07. I weighted 360 to start by June 07, I was at 275,in april 08 after taking some time off my diet i weighed 265 only lousing 15 lbs in almost a year. I started back on my goal and by June i was down to 235 . progress was put on hold in June after a fall breaking my left shoulder leaving me unable to exercise. weight is maintaining, after my next fill in Sept. and getting back to work and a exercise program, I hope to make 200lbs.by Jan 09
