I think you are having HERD (gastroesophageal reflux disease). Stress is one of the Major risk factor for HERD. It is due to laxity of gastroesophageal sphincter. Because of this, the acid of the stomach tends to come up in the esophagus and cause the symptoms. So along with antacids you should follow these too for better symptomatic treatment.1. Avoid large meals, instead take frequent small meals.2. Avoid hot and spicy food.3. Avoid stress and anxiety.4. Go for walk after meals.5. Keep 2-3 pillows under head in bed.6. Avoid smoking or alcohol if you have these habits.7. Lose weight if you are obese. </s>
