i read abook by Allen Carr, and i couldnt recommend it any more highly. that was nearly 20 years ago and havent wanted a fag since.
back then fags worked out at £20 a week, which turned into £1000 a year. before reading the Allen Carr book i had spent 2 years constantly trying to stop smoking with no luck at all, i was a proper addict (or mug). if read properly you will realise its actually a piece of p:ss to stop smoking using this book. after my first year being free of the fags, i went up to chester to buy a "72 mk3 cortina with only 17k on the clock and rare green interior in timewarp condition. with saving up a bit more fag money it didnt long to slam it and put a 2.8i and 5 speed in it.
i can honestly recommend this book to anyone wanting to stop smoking.
there is 2 versions of this book, a thin one and a thick one. id go for the thicker book as it contains more details. you can probly still buy them from wh smith/ebay/amazon etc.
