Any Gastric Bypass patients out there?

I'm brand new here. I had gastric bypass surgery 7 years ago and lost 130 pounds (starting weight was 302 pounds, I got down to 172). I never did reach my goal of 150 pounds, and over the last few years I gained 40 pounds. I am determined to get, if not to my goal weight, at least at what I was down to before. Tracking is very important and I think I am going to like myfitnesspal. Already it has stopped me from mindless night time snacking.
