i weighed 428.5 lbs on dec 1, 2010, and just had the sleeve done last wed. i was told weight loss is very similat to rny, im currently at 384, in a good mood still, no complications, no mood swings, but im sure theyre coming from what ive heard and read. i think the quality of life will be greater with the sleeve then the rny, thats why i chose it.
