Per the Wikipedia page it looks interesting, although I've been almost successful with the patch in the past, and know essentially what to expect. I had used the gum (the gratification wasn't quite instant enough) and the "e-cigarettes" (nicotine vaporizers) before with neither working for very long. I had also tried (ill-advisedly) Adderall, which is supposed to calm nicotine cravings for some. (It really only made me giddy and scatter-brained. A very fun drug that made me almost entirely useless.) Should my next attempt work out the same as my previous ones, I'll definitely look into Chantix.
What's been working for me over the past year is Swedish snus. It has definitely broken me of the 20 year addiction to the process of smoking cigarettes. It's amazing how much of the addiction was to everything about smoking other than nicotine. Snus is a borefest. Avoid any of the American snuses (Camel/Marlboro), it'll turn you off to the idea before you get started because they're sweet and gross and barely have any nicotine. I recommend the "General" white portion and/or mint, and the mini-portions are unnoticeable.
Easy to reduce on because you know exactly how many milligrams you're taking (like methadone or something) because of Swedish labelling rules. I'm hoping to be off snus within the next three or four months, but there's no big hurry because it's pretty cheap and very safe in comparison to other tobacco products.
Internet ordering directly from Sweden is easy, and some of the fancier US tobacco shops are starting to carry it - so you might get lucky.
