30 Foods That Cause Acid Reflux
Alcohol

Alcohol dehydrates the body, which is what causes hangovers in the morning. Being dehydrated can cause poor digestion and acid reflux. It also increases gastric acid in your body. All of this means you may wake up to an uncomfortable burn the next morning.
Alcohol does affect people differently, however. This means that one person with acid reflux or GERD can drink, but another may have severe heartburn after just a small amount.
