[/INST] Hi, Your symptoms suggest that you may be suffering from acid reflux disease. It is unlikely that you may be having an ulcer. Here are some simple measures may help reduce your symptoms: Avoid spicy or fatty food, coffee, carbonated drinks Take small meals Avoid alcohol Do not eat very close to bedtime Lose weight if you are overweight Avoid smoking Avoid stress If these lifestyle modifications don't help, you may need a prescription for an antacid. </s>
