I am 39 and have been heavy most of my life. I have gone on diets and lost some weight, but only to gain it back and then some. I never thought I would have bariatric surgery, until my weight kept gaining and my doc talked to me about the lap-band.
I think the pre-op and post-op liquid diets help with the cravings. It really is like an addiction and right now I'm going through withdraws. I hate it!
