When eating, never lie down! It is important that you sit in a sturdy chair with good posture. Allow your stomach to be decompressed and your esophagus to be fully extended. As you eat, enjoy every bite of your food so that you eat slowly and chew fully, then you may avoid acid reflux afterward.
Avoid certain foods. Certain foods can trigger acid reflux, so it's important to avoid them. Stay away from spicy, greasy or acidic foods, and try to avoid caffeine and alcohol. This is especially important if you are eating a late meal; whenever possible eat dinner at least three hours before bedtime.
