Suffering from Acid reflux - gerd.

I am suffering from Acid reflux for the last 4 years. Last year I was diagnosed with bile reflux since then I am having issues related to digestion. This month I had gone through endoscopy and biopsy. There are no sign of ulcer or corrosion in endoscopy. Biopsy shows traces of acid reflux. I have consulted doctors in Max, AIIMS but they just recommended me to have pantocid tablet. But I am not feeling well. I feel nauseatic for the whole day and uncomfortable above stomach area. I also always feel lethargic. I am on a very strict diet, I don't eat oily or fatty food, have small meals in regular intervals. I don't smoke or take alcohol still its been more than 8 months and I am not getting better. I am attaching my biopsy report.
