Andy,
My mum and dad stopped last year,, in fact it has been just over a year now. They are 60 yrs old and have smoked all their life....my dad was a chain smoker up until him retiring but still on about 25 a day. They stopped thru the doctor..perscribed patches etc.
they have not had a cig since and its the best thing they have done, and they too now realise just how ignorant they used to be with the stinky things
