Eat Green Granny Smith Apples 1 hour before bed.
Also, Purchase a bottle of Braggs Natural Apple Cider Vinegar, A tablespoon of that and a tablespoon of honey, mix it with some warm water in a shot glass, and drink it around noon. It truly helps elimnate with acid. I have always had a huge issue with Acid reflux all my life! So bad now that I am pregnant, But that natural stuff helps!
