Where my brain is... Where is yours?

Congrats to my July family.  I'm scheduled for Lap Band on July 10 and I guess the big that I'm worried about is failure.  What is I don't use my tool effectively?  What if I don't lose?  I'm divorced and don't have kids, so I am really doing this for me.  I don't want to disappoint myself.  I feel like I'm off to a good start because I am on a 2 week liquid diet before surgery and have lost 7.5#.  I just want that to continue.  Let us know how surgery goes.
