The surgery was great, but I'm not down to my target weight, mostly because of bad eating habits. I've lost a lot, though, and I feel great because of the exercise I can do. I had the adjustable gastric band put in, for anyone curious.
Nobody is responsible for my weight but myself, and every time I drink a milkshake, I know that I'm torpedoing my own cause, but I walk 2-3 miles a day on dedicated power walks at a minimum, and occasionally go to the gym at work, so I'm holding my own bad eating habits at bay, even if I'm not gaining ground right now.
The surgery, any surgery, is just a tool, not a miracle cure. My wife lost a lot of weight and has kept most of it off, but we're both looking at our food habits and getting ready to make another stab at fixing our lifestyle stuff so we can USE the tool properly.
Thanks for your concern, though! I still recommend this wholeheartedly over the gastric bypass for anyone who's obese but not crazy-circus-fat. It's less invasive and doesn't require re-plumbing the insides.
