If you don't like bad news don't listen. I was having the same problem several weeks ago. i had been filled to 10 cc and had good restriction. one week later zero restriction. i went in to find there was no fluid in the band. after two more fills under fluro with two different dr's and the same results i decided i needed to go back to my surgeon in Mexico. After three days of test and a lot of hard looking they found the leak. The bad news is that it is near the port inside the abdoman wall. The only reasonable explanation for this would be a failure of the band itself. So after calling the manufacturer do you think they want to help me . If you guessed no you are right. They sent me a cute little 16 page CYA pdf file. Needless to say I am not happy at all. Not sure what my next move will be. I have managed to loose a total of about 85 - 90 lbs in 18 months and have put back on about 15. So i am feeling pretty good but still 50 lbs from my goal. The good news is that I feel good enough to exercise now and I have learned a better way to eat and manage my food. I just hope to gain some faith in that and go forward. But I won't lie to you I am nervouse for what could happen if I am not careful.
