I had my surgery over a year ago and I found that in the beginning you don't notice that you are eating to much or just to fast. Sometimes if you take air down with the food it also causes pain. When I first started intruducing foods back into my body I had to take my time eating. Even if it meant taking an hour to complete something. As I started to loose weight, that is when the band loosen up a bit so that there was no more pain. The first bite can also cause a problem sometimes because I think it is the air that we swallow. Again this is just what I experienced in the beginning.
