Generally smoke around 12-15 during a round.
My record was at teh lombard top club medal a few years ago. Slow play (5 hours or so)and the possibility of a big prize (all expenses foreign trip) rather took over.
I seem to recall smoking the best part of two packs.
I now no longer keep my tabs in my pocket. I find that every time i put my hand in my pocket, there are my fags, and I light one up without really thinking about it.
Toolster, i dont smoke (or play golf either for that matter) becasue i need to. I do it because i enjoy it. You enjoy your hobbies and vices, and I'll enjoy mine, thanks very much.
