Good luck with it. If mediation doesn't work, you could consider a different form of NRT. IIRC, there was a study about 5 or 10 years ago about nicotine receptors and how the different NRT methods can be harder or easier depending on the type of addiction you have. Patches never worked for me or anyone I've known. I did well with the gum, and chewed it for years after I quit. Now when I get the occasional nicotine craving, I totally crave the gum rather than smoking. Cigarettes repulse me now, and I think that the fact that I did give myself the time to want to totally give up nicotine means I put distance between the cigarettes and my addiction.
Best of luck, but I think the biggest secret is if you fail to never quit quitting.
