Congratulations. I had my surgury on 9-1-11 I have lost 25 pounds. I had my first fill this past Wed. didn't hurt just a very weird feeling. I can see a difference now in how much I can eat and I stay full longer. I think it helps not drinking water during my meal. I follow that to the T. My Dr. suggests no drinking 20 min before a meal none during the meal and none an hour after the meal. That has been my hardest adjustment. I hope all goes well with your surgery.
