I was banded Jan 7, 2010. I felt pretty great until about Day 4, which is coincidentally when my pain meds ran out! At that point, I really didn't feel too bad, but it hurt to bend over, my incisions were tender, and then the left shoulder pain started about 5 days out, which I found really strange.
It got better and better. The worst during Day 6 through about Day 10-12 was the fatigue. If you can, give your body a break--after all, you DID just have surgery!
I'm three weeks out now and feel totally normal, except I'm still having intermittent shoulder pain, but nothing I can't handle. I'm on no pain medications and haven't been since Day 4, except for a couple of days of Advil because of the shoulder pain.
What I'm getting from all of these posts is that everyone is different--some recover more quickly than others and we all have different symptoms that bother us more. You are still way within the boundaries of "normal", so I wouldn't worry, unless you don't keep improving.
