Hi, l"m a new member and had aNF almost three months ago. Don"t be afraid although you feel some acid like comming up, you have to be patient because your esophagus is still very swollen from the surgery. It really takes a lot ot time to be healed, and what you feel is not really acid reflux. Eat small portions and try to calm down, because stress is not a good friend in this long healing journey
