Hello friends, my name is abhishek. I started smoking 6 Years back. but left soon for few months, then started and then left for 2 years. 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. Inspite of giving up that f****** thing I am having some trouble. So plzzzzz suggest me what to do....... will this affect my health or I will have some problems in the future.....Please tell me something.....
