Hi! I'm 18 months out from surgery and don't regret a thing (except not doing it years ago). I have lost 105 pounds since banding and about 125 total including pre-op weight. It does take work - you have to make sure you are following the rules. If you eat candy and milkshakes it won't work for you, but if you get your fills and eat Protein and fresh foods it will work. I'm not perfect in my eating because I know from past experience that I can't live my life on a diet, but I eat normal foods in small portions and never feel deprived.
I agree with another commenter that people who are a few years out and successful don't come to the sight and comment as much ( I know I don't), but people who are disgruntled or unhappy do so don't get too down. I have a blog and there are TONS of bandster blogs out there, so I encourage you to read some it really helps you get a good big picture (good & bad stuff).
Good luck with your decision!
