I agree you are not a baby. I was banded on 8/15/08, and I too planned to go to work in a couple of days....well I went on day 6 post-op. Like you, it hurt and wore me out. And, I do not have a k-g class! I had chest pain and now battling a severe rash that several doctors have stated, they have not seen before. But we will be ok, I promise!
Hang in there!!!
