I lost half my body weight in about 18 months. I was left with excess skin on my abdomen, that the insurance paid for to be removed. I feel great!
I know people who have had the sleeve, with great success. At the time I had my surgery, it was a pretty new procedure, and my surgeon thought I might qualify, since my bim was 55, but we opted for the RNY, since it was already approved. I do not get the dumping syndrome, and I only puked twice, at the very beginning.
Your success will depend greatly on your following the instructions. It is hard, and a lifelong battle. You can do it. I know the liquid diet is hard, but it will soon be a distant memory, especially once you are back to your old, active self again!
