I also say Jackie's Story a couple weeks ago. I thought it was a really good show and I liked that it showed how she struggled with the surgery instead of just showing her weight melting off.
I also watched a show that I can't remember the name of it.. it was about a 16 year old boy that was obese and he had a gastric bypass. That was really interesting as well, although they just showed his weight melting away
I do really like shows like these because it lets me see into the lives of other people struggling with basically the same thing as I struggle with. Perhaps not to the intensity of getting a WLS, but the problems and outlook of it. You learn a lot from them.
