I too have not had a fill and feel hungry in the AM. I have since to keep with the liquid diet, did Whey protein shake (vanilla) with frozen strawberries and bananas, little apple juice and blend. They say that protein makes you feel full and not have the munchies. This also helped me continue to loose weight until my first fill which is Sept 7th, hooray. Things will change once that band is filled so enjoy now because you will have to reintroduce all these foods over again with the fill.
Best of Luck.
