I smoked 2 packs of cigarettes a day for over 40 years and have tried to quit many different ways, including nic. gum, cold turkey. This has been my only saving grace! I started e-cigs January 27, 2013. I cut down to 3 cigs a day the first week and as of February 3rd, 2013, I haven’t had another cigarette since!!!!! My wife is a nurse, needless to say…she is very happy with my decision. With a great debt of gratitude, Bobby Holloway
