I was lucky when the FSC showed up, for a couple reasons. First, I owned a house in VA so I'd go down there and "smuggle" months of supply back home that were FSC free for almost a year. Then they adopted the fire suppressant which convinced me to try e cigs. I was coughing badly, it went away with those VA smokes and came back when they changed and it got me finally to the point that I wanted to get off cigarettes. So as much as I disliked FSC, it actually turned out to be a benefit. Even those first 6 months when I was dual using, within two weeks of only the occasional cigarette, about 6 a day, the coughing had disappeared which was very encouraging.
