Please don't be offended, but...
1) Are you active??
2) Are you sticking to the diet??
If you are, then chances are you need to get another fill...
If not, then here's my motivation...Maybe it will work for you.
Everytime I start to "fall off the wagon", I remind myself that I actually had surgery to help myself win the battle with weight. I think about the recovery, the scars, the gas, the pain, and that I don't want it to all be for nothing...It usually works for me. Plus, once you start to lose the weight, you get really excited, and it gets a little easier.
Good Luck! Stay Strong and Positive!! You can do it!!!
