And now, for a minority point of view...
This definitely isn't for everyone. But there will be some people, even if a small percentage of those who need to lose a significant amount of weight, who will find this both acceptable and effective. It probably wouldn't be what I would choose, but that's no reason it shouldn't be available to others. I love my DS, know that it was the right choice for me, but also know that treatment of morbid obesity isn't a "one size fits all" proposition any more than panty hose ever was.
