I smoked for 37 years and was up to 3 packs a day and could barely breathe. My little brother had been vaping for a couple of years and was always bugging me to quit and try vaping. I finally listened Jan 4, 2013 was my last day of smoking and the first day of my vaping journey, I have never had as much as a drag of a smoke since and can’t see a day when I ever will. I now vape 0 Nicotine juice and love the act of vaping so don’t think I will quit anytime soon. I feel 1000 times better I can climb a set of stairs without stopping to catch my breath a few times.
