question: I am suffering from cough for last two and half years. I used to face cough every month for 5-6 days and after getting cough syrup and tablets i used to be cured. But for the last one month i am having cough regularly and even syrup and tablets are not showing any effect to cure it. I get cough only in day time means whenever i do work, i dont get cough a single time in night while sleeping but as i awake, cough is again started. I need to know the exact reason for this, and what should i do to get myself permanently cured from this disease?
