I am a 57 year old male. I had smoked for 40 years. I would smoke anywhere from 2-3 packs a day. I had tried several times to quit, the longest period was almost 1month. That didn’t last long as I went right back to smoking 2 packs a day. The day I decided to try e-cigarettes was the last day that I smoked a tobacco cigarette ! It has been 9 months and I haven’t touched a cigarette. I started on the e-cigarettes and am currently on a mod. I feel do much better now, I can SMELL like I haven’t been able to in years. My clothes and truck don’t stink any more. I can breathe a lot better. I don’t cough anymore. It is incredible what a difference it has made. I am saving a butt load of money not buying cigarettes !
