Invest in a good e cig (the vaporiser kind) they give you the throat hit and plenty of nicotine - it's pretty much the same sensation and a smidgeon of will power will get you across the winning line : )
E cigs stop you coughing and feeling crap in the morning and the feeling of being poisoned. It was easy to get away from the smoke for me - yes i'm still addicted to nicotine, but from a way less detrimental source.
