Banded July 30th. I too gained 2 pounds and was told it was the iv fluids they pump in you during surgery. The first 2 days were the same for me. Just take smaller sips and day 4 was really when all the gas had left me and I was able to sip fluids without discomfort! Day 8 now and my stomach growls constantly but I feel great! Take it one day at a time!
