Remind me to let you know next summer, last roll-up Sat night, I haven't ridden much this year, but I took up cycling whilst smoking, my lung capacity improved greatly, better than many non-smokers in the house, I have quite before, some 25 years ago for 5 years or so, but wasn't riding.
I catch myself sometimes going to want to make a roll-up then I check myself, I can't say I have noticed any pangs and I should be passed the worst of any cravings.
I had a dependency on drink not so very long ago well 5 years, or so, quitting that was hard, in fact pretty brutal to be honest (the first 2-3 days being far worse than anything I have experienced from smoking) so much so it was easier to stay kettled, but I beat that (so far).
I haven't done much cycling these last six months so we will see what the new year brings.
