Gerd problem. Coffee l no outside food.

Hi I m suffering from throat pain n frequent burping n thn my ENT told me i m having GERD n recommend me to visit gastroenterologists.. I consult gastro doctor n he prescribed me to take pantacid IT in morning and prepro IBS at night.. he also advice not to be stressed as it aggravate acidity symptoms as well... Also suggested me to do walking .. I have taken medicine for 15 days n no such relief .. I have done with endoscopy n that shows anteral gastritis and lax GE junction .. After endoscopy again he prescribed the sams medicine pantacid ITand Prepro IBS .. i have it for 10 days n again no good relief... so i stopped medicine and started with ayurvedic treatment.. Now again my throat started paining n irritating me a lot... Again i consult ENT n he prescribed me medicine along with pan D for 6 weeks. .. Is thr any permanent cure for this gerd problem I m still burping though. Also i m taking very normal diet including no spice food l no tea l no coffee l no outside food.
