Yes, many people have succeeded, and you need only "Google" smoking to find the best ways to give up. It's not easy, but just remember that "healthy living" ( regular exercise, moderate alcohol intake, good diet etc) is of limited value if you continue to smoke. I didn't join this Forum expecting to give advice about health, but trust me, I'm a doctor, it's worth giving up smoking by whatever means and however long you have been a smoker.
