Well I've been a non-smoker for thirty years after smoking for the previous ten. I think it'll be great. When I play in a pub session, if there's one smoker in the room I'll cough all night after I get home. After a non-smoking session I'm fine.
I used to work in the Coal industry. I used to see miners go down the pit for 8 or twelve hours where smoking is forbidden and not even think about smoking till they got out, when they'd get a cig from where they'd hidden it in a wall and smoke their way back to the pithead baths. It's all in the mind.
