I smoked for 14 years, I quit for a few months 3 different times over the 14 years. I quit smoking in June of 2008 and then smoked again for about 6 weeks in December (08) and January (09). I ordered my PV on 2/16 and had my last analog on 2/18 (4 months ago)! So, other than 6 weeks, I have not smoked in almost a year!
