I don't know much about COPD, it does sound really frightening. My mom has lung cancer and she quit smoking 20 years ago. All I know is that I'm fed up of weezing often, colds that last and go into bronchitis, ah the smell...it's bad. Yet I'm still anxious about the process of quitting. If I get up early enough tomorrow, I'm going to go to the drugstore to see the pharmacist about a prescription for either patches or another product that would help me. Than either I stop when my pack is over..either this weekend..but definitely at the end of this month.
