Natural Remedies for Acid Reflux Relief

I recently went to live for three weeks at very high altitude, in Ecuador. During my stay my reflux went completely. I found I could even drink alcohol and wonderful local coffee. My symptoms gradually returned about eight weeks after my return. My work involves a certain amount of forward bending so I could be aggravating my symptoms and causing acid reflux with bending. However I do also wonder if the altitude, 8,500 feet to 12,000 feet, contributed to my temporary recovery. Higher altitudes have totally different bacterial fauna and lower oxygen levels. My bodies' physiology had to adapt; with a faster heart rate and thus altered vagal nerve activity for example. Perhaps some of the readers would like to comment.
