Try the ginger root therapy which will cure his heart burn symptoms for at least a year. Buy about 2-3 pounds of fresh organic ginger root in the grocery store. Next, juice the ginger. this needs to be done in either a juicer or shredder but not the blender(For some reason, it doesn't work that well when juiced in the blender). Filter the juice eliminating the pulp. Store this in a bottle in the refrigerator. Every morning, your husband needs to take 1 table spoon of this ginger juice. At first, it tastes like 200 proof alcohol but soon he'll get used to it. Do not eat anything for the next 30 minutes. Continue this for 3 weeks. Keep doing it for the entire 3 weeks even if the symptoms are gone within a week. This easy and cheap treatment would drive away acid reflux for a few months. If heart burn returns, just follow the therapy again.
