It' sounds like you're doing great, you lost quite a lot before surgery. Let your body catch up. I'm sure you will lose a considerable amount. I haven't been banded yet, but it will be in April (I think). I go for all the pre-op stuff in the next two weeks. I'm really excited.
Don't think about losing weight, just think about following the plan and let the weight take care of itself. It will. 1 plus 1 is 2, so follow the plan and you will get results.
Blessings.
