I feel like a crazy person. I can’t stop eating. I’m getting fat. I just want to run around yelling F**K!
Don’t let this person be you. Seriously, just don’t. And you know it doesn’t have to be. In nineteen years, I have heard it all.
Compare that to this:
“I cannot believe how easy it is not to smoke, I just do not have any urge to smoke. Even had some drinks with (smoking) friends Monday evening, I think you might have a few more clients soon.
I think this is it, not a smoker anymore, after 32 years!
Thank you and regards,

So you have tried to quit and found it difficult. Perhaps you know someone who quit and struggled. Maybe you know someone who quit easily, cold turkey and has never smoked again.
What is the difference between all these people and you? Here is what you need to know, quoted from Wikipedia with sources:
Nicotine dependence involves aspects of both psychological dependence and physical dependence, since discontinuation of extended use has been shown to produce both affective (e.g., anxiety, irritability, craving, anhedonia) and somatic (mild motor dysfunctions such as tremor) withdrawal symptoms.[1]

Nicotine Replacement Therapy (NRT) Patch, gum or inhaler?
This Cochrane Review study done in 1996 and updated in November, 2007, found that nicotine replacement therapies like the patch, gum or inhaler increased chances of quitting by 50% to 70%.
Bear in mind that with no program, only 5% of quitters are still smoke free at the end of 12 months. A 50% increase in the quit rate would mean that 7.5% of those using NRT were successful after 12 months. Source: http://www.tobaccofree.org/quitlinks.htm
