One thing people can do is to never eat chocolate or take ibuprofen (and many drugs like it) before laying down. These things relax the sphincter at the bottom of your esophagus. If you pay attention, you'll often notice an immediate burp when you eat chocolate. I restrict chocolate to nothing after 2pm (ish). My gastroenterologist told me to treat my stomach like a hot cup of coffee. When it is full, be very careful to tip it over, otherwise you will get burned.
