I smoked pretty heavily for around 17 years - mostly rollies too.

I also read the Allan Carr book a few years ago now and found it pretty easy to cold turkey afterwards, no drugs, no useless nicotine patches that only make you want to keep smoking, no substituting smoking with lollies or whatever.

Have no had a single drag of a single ciggy since, and now 3 or 4 years later don't even miss it, and don't even like the smell of smoke anymore.
