Well, i've done a few thousand, and the only regret i here patients say is that they wish they had done it sooner. People are often back to work at 2 weeks after surgery.
I just saw a 19yo patient who is 9 months out and went from 255lbs to 155lbs. She was crying
because she is so happy with her weight loss and how good she feels. It's hard work, and not a magic bullet, but you will be happy.
