Chelley,
I'm sorry you are having such a struggle with your band. You know more about the band than most people, but I'm going to ask these questions anyway, because even though I'm sure you know this, it might help someone else.
Are you drinking while you are eating or withing an hour after eating?
Are you taking in any extra high calorie liquids (or soft foods)
Are you drinking lots of water between meals... your body needs the water to lose weight.
Fish is easier on your stomach than chicken and chicken is easier than beef.
If you find you aren't getting your protein in with food... which should be your first choice, try adding low carb/high protein shake once a day - since my restriction is tightest in the morning, I usually have one for breakfast.
If you are doing all these things correctly, I'd say its time to give Dr. Ortiz a call. He really does care about his patients and wants you to be successful with the band.
