Sorry that the band failed for you. When I first decided on WLS, I was going to get the band. RNY wasn't even in my mind! Then I went to visit my surgeon and he told me the that there is a high percentage of people who fail on the band.
So after tons of research and soul searching, I decided on the RNY.
Now, I am almost 2 weeks post-op, and can say that this was easier than I thought...BUT I am 31 and wasn't super obese. I really didn't need much help except for dog sitting, but again, that's just my experience. I think that since you already had WLS the second time around will be harder for you. Do you have anyone close by that can stop over if you need help?
Good luck!
