I've just reached the six month mark and have found this forum so I've signed up to share my experiences :).
I quit with the help of electronic cigarettes which I think are fantastic.
I have a question that I think a lot of six monthers may have wondered about: have I done any irreparable damage?
I smoked from the age of sixteen to twenty one so five years. On average over this time I would say I've smoked twenty cigarettes a day.
I have read lots of contradicting information regarding this. Some people say you'll be back to 100% in ten years, some say you'll only ever be 90% for example.
