Quitting smoking may be one of the hardest challenges you'll face. For most people, it takes several tries to overcome tobacco dependence. If you've tried to quit smoking before but took it up again, think about what struggles you faced and why you started again. What helped you stop cravings and what didn't? What made you pick up that first cigarette after you'd quit? If you didn't use stop-smoking products last time, consider them this time. Or counseling. Keep a journal about quitting. Think what else you can do differently this time to quit smoking for good.
