Good on yer, willpower is the biggest exercise ever, i gave up in march, still get some urges but nothing major and very quickly forgotten, i bought a 50 odd quid excellent electronic cig that just had nicotine and you inhale and felt like smoke and exhaled vapour that looks like smoke very good for quitting or even as a replacement for fags i used it for a couple of weeks then stopped, now my wife uses it now, and the best thing is i have gone from out of breath breathing to slow deep breathing while riding and that is most humbling for me, so its worth it in the end.
