My band isn't working help!!!!

I had lap band surgery a month ago and gained 4 pounds, 4 days ago I got a 2cc fill and not getting full, I can eat allmost a whole sub sandwich before  getting full, did anyone had this problem before? Do i need a much bigger fill? I called my doctor and he said give it a couple of days but itsbeen 4 days help please anyone, what should i do.

it will take several fills to get the right restriction.  I'm sure you've read that in the band forums here.  Your experience is totally normal.  And yes, everyone is completely frustrated by it.  Here you have had this surgery, and it's not helping.

Keep on dieting.  It's important to control your portion sizes so you don't put too much strain on your band while it's still healing.  It's usually the 3rd fill that gives good restriction.  Hang in there.
