I had been a smoker from 1975 to 2011. In April 2011, I started using a E-go style device that worked so well that I, (A 2 pack a day smoker) stopped using cigarettes all together from that time forward. I did how ever get curious after 2 months to see if I was missing anything and lit one up (cigarette). I put the thing right out. Trust me when I say thatƒ??s the last time I ever touched one. Not to long ago I picked up a little bigger MOD (longer battery life). Shortly after that, my wife started using my old one and she to stopped smoking as well. Now to the real story: Was told about 4 years ago by my doctor, that I had lost 30% of my lung capacity due to smoking and that if I were to lose another 10%, that I would be looking at pulling around a green air tank (oxygen tank and mask) every were I go. For the rest of my life! Even after hearing something like that I was having a hard time stopping and man I tried every thing. Gum, Patches, Chantix. Nothing seemed to work. Until, I was turned on to my first E-Cig. And Iƒ??ve not looked back sense. Positive and Negative side for me: Positive; I donƒ??t have that nasty cough in the morning. Positive; I can ones more take a deep breath without wheezing and coughing. Positive; I donƒ??t loss my breath going up or down stairs. Positive; My doctor told me that my breathing has improved. Positive; I donƒ??t smell like an ashtray. (The wife likes that) Positive; I feel so much better. Negative; Canƒ??t think of one thing!!! Sin: Michael Hamilton.
