It is very hard to quit I started when I was 14. I am 31 and have been quit for close to two years because of a heart problem (tho I did quit for 3 years in the past for the same issue at hand). I do not have broncidus every year now and overall feel better but I have not seen where it has helped the heart rythem. I can still say that I do have the desire to smoke one but not as often anymore. I am not sure that you ever loose that desire. I am one of the lucky ones becase I have not gained weight from quiting. I do find that I have a hard time being around smokers not from wanting one but because of the smell. I do feel for anyone who wants or has to quit because it is very hard habit to break. Good luck to all the one who are trying to quit!
