Yes, I'm a smoker. I just started smoking while I was 16 years old. At that time I was not aware of its bad effects. And I used to smoke more than 5 cigarette per day. I started smoking just to pass time. But later it became a habit. Now I reduced my smoking. Now I'm smoking only 1 cigarette per day. I'm also trying to quit because I'm getting very tired after any work that I do.
