Hi welcome to HCM... You have acid reflux because of hiatus hernia..... This can lead chest discomfort...... Follow below advise..... -head elevation while sleeping by putting two pillow under head -avoid precipitating posture like bending , stoopping forward etc... -avoid heavy fatty meal -no food or drink 2 hour before going for sleep -if obese reduce weight ... -fruits more -avoid coffe, pastries etc that can relax LOS The levosulpride you are using can be taken in acid reflux... But if acidity more take omeprazole like capsule which is strong antacid.... Avoid stress and gas forming foods like onion , cabbage, cauliflower , turnip etc..as you have gas problem also. More water..... If still life compromised more from hiatus hernia surgical repair can be done ... Take care
