Very common... and at 5 months he's just getting going on his post-op journey... will last another 18 months or so... many changes come even in the second year post-op. Yes... the post-op journey is quite depressing as the body slowly re-wires itself after vagus nerves are severed. In the meantime... experiment all you want... doesn't hurt... but little meaning to it all because what doesn't work today may be just fine in another 3 months. Don't get down. In the meantime, take some OTC Mucinex... usually helps a bunch. I'll assume he doesn't have a cold or flu or Covid or some other infection.

And never think you're in the clear... getting to one year still declared as NED is a biggie. Getting to two years NED really has meaning. Scans and blood tests and endoscopies will tell the tale. I'm come privately to chat as well. Hang tough.
