I have been suffering from gerd and anal fissure both since August 2019. For which i took medication. After taking acogut and bravia dsr plus  freego with lactulose medicine i got ok within 1 week. But again in march 2020 I faced the same problem Dr advised me gaviscon and nexpro 40. I am feeling much better but after stopping these medicine my problem is still same. What type of food I should take to relieve my symptoms of belching,hiccups and bitter water taste in my mouth. Also should I take apple vinegar in my regular diet?
