Hyperacidity & Cough issue. This issue?

I have been having hyperacidiyyu issue since over a year (heartburn, acid reflux). I almost always eat home food now, stopped having tea even, stopped consuming colaetc But since last 3 mths or so I cannot live without having a Pentocid 40 tablet every morning (earlier I used to take Zinetac but that doesn't help that much as Pentocid does). The acidity is in control but I get a lot of constant cough, coughing (khansi) doesn't help to bring out phlegm, there is slight wheezing while breathing sometime. I have also started snoring a lot with open mouth which sometimes cause intense dry mouth and throat causing me to wake-up during night. I don't want to go surgery route and absolutely fear endoscopy. Is there a natural solution to this issue? Can using Pentocid daily cause any side effect (I am also on Telma 40 for BP). Behaviorally, I can tell you that I am a very hypochondriac guy, very self-centered but I am not under stress or anything. I don't smoke or drink. I am currently 45.
