I have only been banded a short while, but will relay my Aunt's story to you. She was banded three years ago at the same time some of her friends got the sleeve. She is still maintaining within a +/- 10lb range of her goal weight while some of her sleeve friends have started to gain again due to the aforementioned stretching. She did warn me about PB's, and did have some problems with her band due to being severely ill twice, but she still loves it.
I like the fact that I have all my anatomy still, and that if something happens, it can come out. I also like that I can lose weight normally and so it is less obvious to people who don't know I've had it done. Also, I think it's important to note that the recovery time for the band vs the sleeve is much less. This was really important to me, as I manage a restaurant and could not be gone for too long.
Since starting a low fat diet about three weeks before surgery and then transitioning to a pseudo liquid the week before surgery, I have almost lost 30 pounds. I am happy. I have been a slower loser post-band, "only" losing about 9lbs since my weigh-in on surgery day, but I am over the moon.
