Max and JAM,
Are you both still on PPIs? If not, you should be. During healing, as we've said many times, it's possible for some reflux to sneak by the wrap. Also LPRers are far more sensitive to small amounts of reflux than the general Nissen population, so it's even more important to be protected.
Believe me, I know what you're feeling. When I had my surgery, I didn't see any improvement in my lungs for two-and-a-half months. It's hard to be patient, and it's natural to worry.
The six month mark...and the year mark...they are reminders that your upper GI tract has been totally revised, and it takes that long for it to adjust to the changes. Those discomforts in the wrap area, vagus nerve irriation, swallowing issues, bloating, swelling, etc, etc, etc...all those things will take time to resolve.
I was experiencing intermittent dumping through the first year, and figured it was something I'd be dealing with forever. Yet, somewhere in the second year (I can't pin it down) I suddenly realized that it wasn't happening any more.
In my experience, it takes time for inflammation of GI tissue to calm down.
I know it's hard to wait, and hard to trust that it will happen.
