Yesterday night I was having severe pain in chest because of acidity :( I took one 'pudin hara' tablet before sleeping and drank lots of water. But then again at about 2 A.M. , I woke up due to pain in chest , so I took one more 'puding hara' and slept. The pain was reduced slowly.

This doesn't happen to me frequently but I am really scared as the pain was unbearable.
Suggest me some home remedies /eating habits which will help me fight the acidity.
I am 26, F.
