HI - I chose the sleeve after attending the classes that Kaiser requires their patients to take prior to the surgery. They are really against the band as it is a temporary thing that has to be adjusted and can cause other issues with corrosion etc. Also the way I understand it is that the band makes a small puch but you can eat anything you want- just smaller portions of course. With the Sleeve you get sick if you eat too much sugar or fat and I am a sweet craver so for lots of reasons I think the sleeve was the best for me. I am very happy at day 4 - no real pain at all, just sipping water and protein water and I have had a couple of sugar-free popsicles. I am very happy and excited about the decision. Good Luck with your decision.
