Yes I got my band just over a year ago. Personally I have had no troubles, but I accept the possibilty that I could have a slip or require maintence of the band over my life time. I also went into it with semi unrealistic expectations and learned along the way it still takes dieting and some exercise (not that I can claim to have done much in the way of exercise, but I have no doubt I wouldn't be at a standstill right now if I would just commit to regular exercise).
I would absolutely do it again even though my average has only been 1.3lbs per week and I was sometimes disappointed that it wasn't coming faster. The pace I have lost has always been linked to my direct effort. If I dont try I dont lose. Don't panic, just do your homework. If you want something to make dieting easier, to not be so led by your hunger, and to keep you full longer this may be for you. Likewise if you need something that instead is going to keep you losing when you are eating fattening foods, and the weight will come off quicker, but you dont mind upping your vitamin intake or a more intensive surgery ds or sleeve may be a better fit. Best of luck!!
