Oh, please don't start!! I'm an all or nothing kind of person and had to give up completely. (Many years ago) Now I've become completely intolerant to anything smoking related. So much so that I gag and almost vomit if anyone smokes around me, if there is a dirty ashtray near me or even at the look of a cigarette box. It is extreme, I know but I really hope for your sake that you don't start.
