It sounds like there is not enough Fluid in your band cause your suppose to feel the restriction after your fill. At the doctors office I work at the doctor gives you some Water to make sure it goes through your band good enough and you don't throw it up. But to me it sounds like you don't have enough and it makes you over eat. But I can always find out when I get back to work I'm out of the office this week and I can fill you in on some more about it
