hey, crimsoncutie,
I have had the same experience you are having for two different reasons. Yes, sometimes you have to go with liquids and soft foods for a short while (usually 2-4 days for me) after a fill. I have had my band for 18 months now and whenever I have a head cold with mucus drainage, I notice that I cannot eat much at all. I have assumed that the mucus is draining into my stomach and filling me up and that is why I cannot eat much when I have a cold. I hope this helps.
