I know two people personally that have it done... both were more than 100 lbs overweight as well. It is not a wonderful solution... my father is one of those people. He had it 20 years ago, and while medicine is more advanced... he's struggled for the past 20 years with gastro-intestinal problems directly resulted from the surgery as well as constantly trying to adjust to his "new" system. And as WI pointed out, I would be shocked if you can get it covered. Very few insurance companies are still covering it, even when medically necessary. I'd consider discussing options with a dietician or a personal trainer as maybe the exercise or diet aren't working for your body.
