Don't allow yourself to be brainwashed. That is, don't let yourself believe that you need a cigarette for ANY reason. The truth is, YOU DO NOT NEED THEM. Your mind will come up with all the clever excuses. We know them all, there are simply too many to list here. Do not focus on that side of things. Do not focus on the negative aspects of a quit, which involves your mind and excuses. Focus on the positive side by telling yourself "I don't do that anymore" as many times as it takes, no matter what other ideas pop into your head. So basically, if cousin Jimmy goes to the hospital with an illness this week, don't say "I need a smoke because my cousin is in the hospital." That is not the truth. That is a fallacy that won't make you or cousin Jimmy any better. There are two things to say;
1) "I don't do that anymore"
2) "smoking is NEVER an option"
Adhere to both of these statements, and you WILL succeed in your quit. All you have to do is realize the truth. Do not fall victim to the brainwashing of nicotine. That is what kept you smoking (most of us for several years). Open your eyes to the truth. See cleary without all the smoke getting in the way.
As I like to say, there is only one rule to a successful quit; DO NOT SMOKE. Living by these rules, I have been smoke free over 600 days! You can do it!
