Have you explored cutting out alcohol and "junk food"? My wife and I did and it cured us of acid reflux within weeks. Before that, we always went out and partied, ordered Grub Hub, wings/beer, etc. We both had it so bad, doc had us on meds for it.
That stuff will destory you internally man! I can feel it after having pizza just once a month.
If it's not the diet causing it, I used to do a shot of Apple Cider Vinegar every night before bed and it neutralized about 90% of the feeling.
