paclift13

I'm not sure if anyone can help but heres my story. I had my surgrey on 9-9-13 and lost 20lbs the first month. Going into my 8th month and several fills (7.7cc) I am struggling to lose weight. I have gained some back and am stuck not losing any weight the last 3 months. I eat less than 60grams of carbs daily and around 100 Protein. I have 2 bad knees so i dont work out as much. I swim and ride an exercise bike. I dont know what else to do. I feel no restriction. Please help i'm about to give up.
