after that I used to smoke occasionally, like in parties or weekends, or
with my friends. Then, 1 Year back I had a break up
with my girl friend, I started a vulnurable smoking. I continous smoked for 6 months, but thank god..... just because of my will power I left it. Now I don't smoke at all........ but now sometimes I feel pain in the middle of my chest, whenever I laugh, I lie on the bed, I get up in the morning, or I sneeze, I get dry, and black coloured cough. I am scared now.
