If you have tried to quit smoking, you know how hard it can be. It
is not easy to quit smoking. It takes a little practice. Most
people try to quit smoking at least once before they quit for good.
Each time you try to quit, you can learn about what helps and what
hurts.
Remind yourself that your first cigarette did not make you a smoker
to start with, and a small setback does not make you a smoker
again. Quitting takes hard work and a lot of effort, but you can
quit smoking. Staying away forever takes a serious effort,
involving changing behaviour and comfortable lifestyles.
If you want to stop smoking, get help. And the more help you get
the better your chances of stopping for good.
