Fire safe was the beginning of the end for me enjoying a good cig.. I even went as far to re- tube my M-reds into zigzag tubes to loose the FSC chemicals and get my flavor back.
Have to agree they made me feel sick too..
Yep yep, that was the path to ruin for me as well. After FSC was added every cigarette tasted like an ashtray (I'd know, I've licked one on a dare before, ugh), and it was frustrating to smoke, because your cigarette would go out constantly while you were smoking it and then when you set it down it would burn down the rest of the cig (at least mine always did >_> it's like the FSC was meant to make you smoke more cigs).
I actually enjoyed smoking cigs before FSC was implemented (well, minus the morning cough, but the FSC made that a LOT worse, it got to the point where it was like having an asthma attack).
To summarize my symptoms from smoking: morning cough, phlegm, airway constriction, coughing, fatigue, insomnia, and sometimes headaches.
Also lung/throat pain sometimes upon inhaling, though not constant in anyway (sometimes it'd happen once a day, sometimes once a week, really inconsistent).
