I also had acid reflux and went on a low carbohydrate diet (Atkins) and the acid reflux disappeared THE FIRST NIGHT! I learned that too much sugar and too many carbs which convert to sugar in your system can cause an imbalance and you can get candida overgrowth. I got some powerful acidophilus pills at GNC (4 bill live organisms) and that helps a LOT if you take one before you go to bed. I also got Active Digestive Enzymes by GHT and FiveLac by GHT. I found the enzymes to definitely help if I took them with each meal. I read in a book that as we age, we lack digestive enzymes so I have incorporated them into my treatment. I would of course advise you to go to a doctor as well, just to be sure, but I did not do so. I literally had sharp pains in my stomach in the middle of the night which would awaken me and I no longer have those pains at all. It very well could have been a food allergy. Good luck.
My acid reflux is entirely independent of diet. Can eat anything or nothing — no difference until I take Prilosec or Famotidine. This is not unusual. I could not possibly swallow anything untreated. Have tried the enzymes also and they helped some but no where near sufficient by themselves.
