Chew cinnamon gum after meals.
Chewing gum stimulates saliva production, which helps to neutralize stomach acid. Gum chewing also encourages frequent swallowing, which clears irritating acid from the esophagus more quickly. Just make sure to choose non-mint flavors, since peppermint and spearmint can relax the LES and exacerbate symptoms. Pick up cinnamon or fruit flavors instead.
