Any magic bullets to cure GERD naturally?

I have really bad acid reflux. I know I can take prilosec, but if I can cure it naturally then I’d rather do that.
I wonder if anyone knows if there is a way you can tell if it’s a function problem, re: your esophagus doesn’t work properly, therefore it never will so yes you need to take medication, or if it’s a dietry thing?
I suffer quite badly from an anxiety disorder and I’ve had heart burn for as long as I can remember.
However, I dont want to be stuck in a vicious cycle with medication and I believe the body to be capable of healing yet I can’t seem to heal this and it’s really affecting me, also I don’t want it to eat away at my insides and cause cancer. ;)
Thanks for any help – natural help, I’ve been to see the Dr many times, however here in NZ it’s very hard to get see a Gastro Dr – unless you’re really sick they just don’t do that unless it’s private.

Thank you.
