You are doing great. I was banded 08/13/09 and I have lost 66 lbs between pre and post surgery. I too went for about 3 weeks with no loss and was so frustrated, but then in about 5 days time, I lost 12 pounds. It is crazy how it works, and it has now happened twice since then. I am thinking that I am going to do that pretty consistently. During the first 3 week period of no loss, I dropped a pant size though. So, definately start taking measurements. Maybe you are building muscle, which weighs more than fat, and it helps you burn fat faster, so it is a good thing.
