Noodle - I had Gastric Bypass Surgery myself. And to be perfectly honest, if I was told I needed to go back in again tomorrow - I'd sign up in a heartbeat!!!!
Even with the risks involved (blood clots/complications/etc) they are the same or even a little less than lots of other common surgeries people go through.
A little about me - I was 640 # in Dec 2001 when I had my surgery. Now I haven't weighed in 3 weeks or so but I know I'm below 300 # for the first time in years!!! That's a loss of 340+ pounds in 17 months!!!
