Firstly we have to diagnose your problem,simple heartburn
may not lasting for so much time.so we must rule out possibility of peptic ulcer
,acid peptic reflex,gastritis
So once you consult the gastroenterologist and get it diagnosis with few investigations.

Avoid spicy and chillies food,avoid junk food,
Ok and take care.
