3 stone is a great amount of weight to loose. I always find that if my head isn't in the right place, I can't loose weight, band or no band. I've struggled to get my last stone & a half off & ive joined slimming world. It's helped me so much & after 2 months of my head being in the wrong place, I've got my mojo back & im loosing again. Pm me if you need to. I've had my band nearly 18 months now & I'm happy to help in any way I can.
