I had the same experience. On thursday I had another 1cc put in and I could drink water fine when I left, but when I got home that evening I couldn't drink water or anything. I went back on friday and he took out .5 cc and now the band is working great! Before this last .5, I could eat a couple cups, but now I stay full longer and am satisfied with much smaller meals. My doctor is pretty aggressive with the fills, I can go back every week and get a fill if I want too.
