So as a five-year pack-a-day smoker, I've got pretty much all of the maladies associated with smoking. All my clothes smell like smoke, my fingers are slightly yellowed, and I cough up all kinds of horrible crap every morning. I bought a Blu, and for three days, I didn't even think of real cigarettes. Then both atomizers died, and I had to switch back to analogs. The consequences, of course, were awful- my body decided to fight back after the years of abuse. For a week and a half I felt like absolute death. I recently received my Revolver Elite, and I'm four days in without real cigarettes. I love this thing. The vapor production is awesome and the carts last pretty long. I'm not irritable (at least not more than normal), and the morning hack is almost gone. At the time of writing I'm about to go out drinking for the first time with the e-cigarette, so I guess this is the real test, but thus far I feel better and better every day. Maybe I'll even go for a run tomorow. Maybe. Probably not, though.
