You had surgery 2 weeks ago. Didn't your doctor tell you that your body is healing the first 6 weeks or so? Right now you are on the restricted diet while the swelling goes down and to build scar tissue around the lap band. You probably haven't had a fill so why would you feel full? If you really wanted to you could probably eat a whole pizza b/c there probably isn't anything in your band. Take it easy and heal first and then get a few fills before you wonder if your band is working.
