It is hard to quit smoking. Everyone knows it, but if you are seriously concerned about your health and want to leave off the smokers, you can do it. The problem with an addiction like that of smoking is that it's not just a habit to be broken, your body also has a physical need for the drug contained in the cigarettes.
To quit for good, you need to be determined and prepared. If you are still sitting on the fence about whether or not you should quit, or are only quitting because you bought to and not because you want to, it is probably not the right time to undertake this great task.
The first step in quitting smoking cold turkey is to make the decision that you will quit and that you will never touch another cigarette again. Then start immediately. No "one last smoke" or anything of the sort. Try imagining your life without smokes, how pleasant it will be and what improvements will be made. For example, if you have breathing problems due to smoking, imagine being able to walk up a hill quickly without running out of breath. Positive thinking is the key in staying upbeat about the whole quitting process. Even if you are not into visualization, it does help to stay positive.
To help you make the jump from smoker to non-smoker, try writing out a list of reasons you want to quit. Stay away from generalizations like "Health" and get specific. "I do not want to end up like Uncle Lenny with lung cancer" is far better. Hang the reasons on your fridge or keep them where you normally store your cigarettes so you can read them over whenever you feel like lighting up again.
Quitting smoking is not pleasant, you will suffer from withdrawal symptoms, but these will disappear within 2 weeks, if you are quitting cold turkey. Also, the majority of relapses occurred within the first three months, so if you can make it to that 3 month mark, you are good. It helps to have a specific goal like this, one that seems achievable, rather than the ominous thought of never smoking again.
Knowing what your triggers are will help you identify and avoid them when they come up. Most people smoke more when under stress, so try to avoid stressful situations. If you find that you can not avoid the stress, it might be best to wait for a less chaotic time in your life to quit smoking.
It will take a lot of perseverance and hard work to quit smoking, but you can do it. Thousand of other smokers have managed and you can too. If, for some reason, you fall off the wagon, just remember that most people who have successfully quit needed a few attempts to do so.
