Hi. Thanks for your query. Noted your history of acid reflux, trying to create diet but still have heartburn in the chest area, wants to know whether doing anything wrong... The basics of management of acid reflux is as follows: Try to find the instigating or enhancing factors, foods, beverages and stop them altogether. PPI like Omeprazole to suppress acidity. Domperidone to regulate the motility Antacids whenever on empty stomach. Soft bland diet, small frequent meals. No late nights. Sleep in reclining position. Upper GI endoscopy to see the primary and secondary changes and get treated accordingly. This way you can get the relief.
