I am suffering from chest burn due to acidity from past 2 years. Most of the day time i am all right with no problems, but after having dinner, and during sleep, i get lot of chest burn and if i sit for some time...it dissappears. I would like to know the reason for this. Due to this problem, im having throat irritation as well..I am eating lot of cucumber, papaya..but the problem still persists. I have taken lots of tablets..but its has not cured.
