I disagree with all the previous posters. Lapband, the sleeve, nor RnY is the answer for you. Sure, a malabsorption surgery may be better for you, but in the end, no surgery, no doctor, no diet, no NOTHING is going to "force" you to lose weight. Maybe you should talk to a therapist or some other professional who will be able to better understand and help you.
Nothing in this world will force you to loose weight, unless you're locked in a room without food or Water for months on end. It comes down to how bad you want it. You need to track your calories, exercise, and have some willpower to want to lose weight. Surgery isn't the easy way out; there isn't one.
