Hello Smoking actually aggravate acid reflux, though indirectly ( as few patient feel that they get relief due to smoking , this is actually misconception ). Following measures may be useful for you to get rid off this acid reflux. Try raising the head of your bed about 4 inches with blocks . It might also help to avoid eating or drinking for 2-3 hours before you lie down. To help control stomach acid one should not drinks with caffeine in them . Avoid greasy or spicy or oily foods , don t eat chocolates or pizza or burger or sweets . Also take some antacid but if you feel severe acidity you may need drugs like proton pump inhibitors like pantaprazole -d once or twice in day till complete relief . When such patient visit I advise them to take rebamipide 100 mg 2 tablet twice in day for 4 weeks . Since this is a prescription drugs , so consult your physician and get a prescription. Over eating is the another reason of such symptoms , so please be aware about that also. Tension and anxiety are another most common reason of such symptoms , so be careful. Hope these measures will be useful for you. Good luck.
