Hi, I am 4 weeks post op. I lost 15lb from the pre op and the following 2 weeks, but nothing since. I'm having my 3 meals a day, 1 snack no large amounts of food. Why is no more weight coming off. got 4ml's in, got my first proper fill on the 26th. Any advice would help, as I'm kind of thinking why have I had this done !!!!
