E-Cigs are the way to go.
They sell the juice with varying amounts of Nicotine
I started with 24mg per 30ml bottle,vaped on that for 3 weeks and then went to 12mg. Vaped 12mg for three weeks then went to 0mg Nicotine.
I was vaping no nicotine and my body couldn't tell the difference since I had progressively weined myself from Nicotine.
Occationally I still crave a cig so I use my 0 Nicotine E-Cig to stop the urge and all is well.
BTW I smoked for 35 years,a carton a week and had never tried to stop at all,I got tired of the prices going up and up and the health factors so I went to the E-Cig.
Nicotine Patches,Gum and prescription drugs to quit smoking
are VERY expensive and aren't that effective.
E-Cigs are cheap and at least if that doesn't work for you not much spent.
