I'm about 4 months out from my Nissen procedure. Some food I still have problems getting down (sticky things, or when I don't chew enough). When I do experience that I stop and think "What am I doing wrong?" and it's usually because I'm eating too fast, not chewing well enough and not cutting my food up into small enough pieces.
Be careful and be good to your wrap!
