I am in my early forties and have smoked since the age of fifteen. I have previously tried quitting with all the commonly recommended methods. Chantix made me depressed, completely flattened my mood and made me generally miserable. Neither the patch nor gum helped @ all and quitting cold turkey I only made it two weeks. I had resigned myself to being a smoker until the day I died. Then, thanks to a close friend of mine who managed to kick a forty plus year habit, I tried my first e-cig. It was amazing, within a week I had completely stopped smoking. It has now been almost four years since my last cigarette (Oct. 2010 was my last). E-cigs are useful because they address all aspects of the smoking addiction. The hand to mouth action, the mouth-feel, and physically seeing the vapor while I was vaping. I will also add that having different flavors is very useful in stopping smoking. Hopefully my testimonial will help someone else quit.
