I had my lap band surgery Oct 1, 2011. in las vegas, NV, By Dr Soon, everything went well, the first few months, even the first year,had some fills, was not even at 50%, I felt full when I ate , no snacking, after a fill. Then about 6 months ago i started throwing up, everytime I ate no matter what it ws, even during the night i would throw up, Finally went in and they took almost all the Fluid out, Instant relief, something must have been stuck in the band, But sense then I have had 3 fills am over the 50%, but feel NOTHING, I have gainned back 20 pounds, I am so disgusted with myself, as I feel like an eating machine, I have even started drinking alot of diet soda, hoping to feel full, anything, i feel nothing, they say the band could not have come loose, or slipped, but I really don't believe that, as why am i not EVER feeling full, and am hungry ALL the time, any help would be appreciated.
