I will say it may be cheating but I went from two packs a day down to none. You ask how this can be done in just a few days? The trick is called the vapor. The key is to find a flavor you like in it. Yes first try I failed in the switch. Than after a few months I decided to give it a second try. I went down and sampled the flavors this time and found one I liked. Since that day I have not looked back and dont miss the old cigarette. In fact the smell is very offensive to me now. If your thinking of quiting try a vapor you will be surpised and happy with the results.
