Oh yes. I felt that way many times in the beginning. The first several weeks are the hardest because you're still recovering from surgery, you have a lot of restrictions on what you can eat, you have to drink nasty protein shakes, and you haven't lost enough weight to feel the benefits of the surgery. Once you get to the regular foods stage and get the benefits of weight loss, things will get a lot easier. I'm almost two years out now, and that miserable newly post-op stage feels like a lifetime ago -- just a tiny blip on my journey to losing 200 pounds. Hang in there!
