Failed again

I had lapband surgery on 10/15/10. Have lost 60 lbs and 50 of the lbs I lost in the first 4 mos and only 10 lb wt loss in over a year. I feel like such a failure. How do I get back on track??? I've tried so, so many times and just can't do it. Seems like I just can't get a right adjustment. I'm either too tight and can't eat or eat too much. I last saw my surgeon in Feb and he gave me a fill. I've had difficulty eating due to frequent stuck episodes, so I eat the bad stuff.  I had an appt with my surgeon in last month, but cancelled it because I was so ashamed to go in and not of lost any weight.  When I first saw my surgeon he recommended gastric bypass over the lapband because of how much weight I had to lose, but I was convinced that the lapband was going to work for me and I was going to show him that I could do it. Well I was wrong.  Does anyone know what the criteria is for a revision?
