If you overeat, trust me you know it. You either throw everything back up or have this horrible discomfort in your pouch area. As for stretching your pouch out, it takes months and months to do. When your pouch is created, its created with the knowledge that it's going to stretch. My surgeon makes the pouch so that when it's stretched it will be the size of a small orange. Other surgeons make is different sizes, but that's pretty much the norm.
You need to get into the mindset that you did the most wonderful thing for yourself by getting the surgery and know that this is what is going to work. If you keep thinking that you're going to fail, you're going to drive yourself to fail. It's all mind over matter. Tell yourself you are going to succeed and lose all the weight you want to and you will be fine!!!
Focus on how much you've lost! Celebrate it!!
