Acidity that has been troubling you for years usually means your stomach acid is not being well-controlled by your current routine. Try spacing your meals properly and keeping them light, and avoid going to bed soon after eating so the acid does not move upwards. Cutting down on foods that worsen symptoms, such as spicy foods, fried foods, tea, coffee, and late-night snacks, can help, and sleeping with your upper body slightly raised may reduce nighttime discomfort. Adding gentle daily activity and keeping a calm routine can also support better digestion. Watch for any increase in burning, difficulty swallowing, or changes in weight. It would be best to consult a doctor who can review your treatment and suggest a more suitable way to manage it.
