I'm sorry to hear that you're experiencing persistent burping and acidity after meals. These symptoms can be caused by various factors such as acid reflux, gastritis, or dietary habits. If you have been taking medication like Sucral Tablet (which typically contains sucralfate, used to protect the stomach lining), but haven't noticed improvement, it might be due to:

• Inadequate duration or dosage of treatment
• Underlying conditions that need further evaluation
• Dietary or lifestyle factors that are not addressed (e.g., eating large meals, fatty or spicy foods, smoking, or stress)

It is important to consult a gastroenterologist who can assess your symptoms thoroughly, possibly recommend investigations like endoscopy, and tailor treatment accordingly. Meanwhile, you might find relief by avoiding trigger foods, eating smaller meals, and not lying down immediately after eating.
