I'm almost 15 weeks post op and have not lost any weight in over a week. I feel like I'm hungry more and I'm able to eat 5-8 bites now instead of 3-4. Does this sound normal?

Oh yes! What to do is not to panic. Stick with getting your protein and fluids in, along with exercise. Keep doing what you are meant to and don't get down about it - your stall will eventually break. I had a stall that went on for a few weeks, I kept going and eventually the scale plummeted! Good luck....
