I was banded almost 8 weeks ago, and just had my first fill. I'm VERY upset that I still feel no restriction and only once have had anything "get stuck" while eating. I'm very worried that the band is not going to work for me. Aren't I supposed to feel full after eating a half to 1 cup of food? I keep waiting to get that "full" feeling and it doesn't come. What am I doing wrong???
