I have smoked for 40 years over a pack a day… I tried quitting in the past using the patch which did not work, it made me want to smoke more. I tried chantix, horrible stuff, it made me want to kill myself and a friend made me stop using that stuff cause of that and it made me a very mean and crabby person also. I tried cold turkey, wow that did not work, surprise , lol…a very special family member bought a vapor e cig for me and much to my amazement I quit after 6 days of using it , I cut down to 5 cigs the first day. My doctor actually told me that in his opinion ( he had to say opinion cause there has not been medical proof to this) the vapor will actually help my asthma and WOW no asthma attract since I have been vaping… I live in Illinois where smoking is not allowed in public areas, even outside, and even though I quit smoking only 2 months , I still go to Indiana for many things I do because I still feel freedom is important. Restaurants have such good ventilation I can not smell smoke when I go to a smoking restaurant, and boyyyyyy can I smell things now that I quit smoking. I am 53 years old and I used to feel 73 , now after only 2 months of not smoking I feel like I am young again. While I have been using the vapor mod , I have not even gone through those mean , crabby , depressed stages. A great big thank you to who ever came up with this, you sure made my life much much much better.
