I had my first fill a month post op, and my second one a month after that and my 3rd one 2 weeks after that but only because I called them and told them I was making very poor food choices and I didn't think the fill was working. I am scheduled for an appt. on 3/21/2011 and will probably get another fill then.
Good Luck to you and stay positive - remember the band is a tool for weight loss NOT a solution -you have to work at it every day - both mentally and physically.
