What appears is that you have something known as gastroesophageal reflux.
Avoid Junk food, tea, coffee, alcohol and smoking.
Add curd to your diet.
I do not know why are you taking Abflo--- unless untill you are asthmatic.
Just take Tab.Pantocid 40mg once a day x 2 weeks.
Next Steps
If there is no relief in Symptoms probably you will require an Upper GI endoscopy.
