I'm newly banded....I had my surgery on 8/29/13 and I returned to work on 9/3/13. The first couple of days were tough. I was very sluggish and I had brain fog. But, I tend to think that it had alot to do with the fact that I was still on the clear liquid diet. Once I was able to move to the next phase of the post op diet, I felt much better. I had to also make sure that I was getting as much liquid as possible, getting in as much protein as my body could handle and taking a multi vitamin daily....Hang in there, it will get better
