Likely to be flamed but here is my opinion (Waiting for GA to enter this thread):
It can help you wean yourself off nicotine with gradually lowering the amount of nicotine you consume.
There is no such thing. Nicotine addiction changes the makeup of your brain in such a way that it is nearly impossible to "cut down" or wean yourself off. This is why "light" cigarettes were such a poor idea (besides that you actually got more nicotine from them than "full flavor") Your brain creates more and more nicotine receptors and eventually levels off and you must maintain a certain serum level for your brain to be satisfied. It is "changeable" as folks do seem to be able to adjust their intake levels slightly, but for the most part, you need to be intaking nicotine roughly every hour-3 hours to stave off the withdrawal symptoms.
Your body will go through a roughly 72 hour period of physical withdrawal. Every time you intake any appreciable amount of nicotine, that timer is reset. Now your body doesn't just want a puff. It doesn't want a little bit. It wants that level it has been used to for so long. So if you give it just a puff, it'll restart withdrawals, and you have to go through the 72 hours again.
So why prolong the inevitable? The commercials for Nicorette or the patch are written by a company with an interest in keeping you addicted to either the gum or to keep you "trying" to quit. The product they sell you resets your addiction for another 72 hours. So it doesn't "suck less" at all. It just makes it suck forever.
Nearly everybody that I know that has "tried" to use gum/patch/zyban has failed. I count 29 people personally that are still smoking. My mom being number 30 that I know - it worked for her. I know of 8 folks who have quit cold turkey and are still quit today after 3 months. Just about everybody that has failed at cold turkey also went to the gum, including myself, so consider that I know about 39 people right now who are still or are currently quit smoking.
Just stop smoking. You really need to give it your all, you need to really want to quit, you really need to just resolve that you are never, ever going to smoke again.
I think that is really the key, and lots of folks think its too hard so they can just spend money on it.
You are going to have some pains, most likely you are going to fear your new life without smoking, but you can relearn how to live, without puffing away every hour of your life.
Hope it works for you and PM for more info and encouragement.
