Hi D.,
My cousin actually had this done, and had the story broadcast on the local news. He is losing a ton of weight, and is feeling great. He had to go through a bunch of counseling and meetings with doctors before he could have the surgery and even had to begin dropping a percentage of the weight before his surgery.
It was an outpatient surgery, he was scheduled to be out of work for two weeks, but went back after just one. The first two weeks was pureed food only and you can only sip liquids.
There are a loads of upsides to this surgery as opposed to a full gastric bypass surgery, being adjustable and fully reversable if necessary, it truly has been a godsend for him.
Best of luck in your reseach, there is no easy answer to losing weight, I am involved in the weight battle myself, I am slowly pecking away with Weight Watchers online.
Take care,
S.
