I started to smoke when I was 20. I started it for fun, but gradually, smoking became an unavoidable thing in my life. I smoke a pack each day. It has been only some time since I had feelings to stop this. The main reason was, my friend was diagnosed with lung cancer some days before. He also used to smoke. I became so afraid after hearing his case. I decided to quit from that day onwards but, I was not able to do so. I had a craving for it. Since I can't control myself, I think it is better if I undergo a smoking cessation treatment at Toronto. Is there anyone here who has undergone a similar treatment? How did you quit your smoking? Please suggest me some ways. Is it necessary to undergo a treatment or is there something I can do by myself? Please share your thoughts.
