Considering Gastric Sleeve Surgery - Looking for Testimonials

My gynecologist recently referred me for something called a "gastric sleeve". She says given my size, and everything I've done to try to lose weight, I'm a good candidate for it. She says that the gastric sleeve doesn't come with the side effects that a gastric bypass or lap band come with. she's referred about a dozen patients and all have been very happy with the outcome. she's seeing an average weight loss of 50-60 pounds in 6 months. but I'm a little nervous about having surgery bc last time I had a bad reaction to anesthesia and ended up on a ventilator in the ICU for 2 days. So I'm interested in some testimonials from actual people. what experience/knowledge do you have with this particular procedure?
