I have GERD. I wasn’t born with it, it developed when I was 20 years old. Sometimes it gets to the point where I vomit multiple times a week and even damage my esophagus sometimes. Tonight that happened to me and I got violently sick. After a little bit when I finally felt hungry again I ate yogurt. It completely helped my stomach feel better and made my acid reflux go away. Also, if you don’t mind the taste, swallowing a tablespoon of mustard works well too!
