Where are the threads on over-vaping/nicotine dosages? I can't seem to find them. I really think I'm over-doing it with the e-cig. I vape as much as I ever smoked, but it seems that I'm getting WAY more nicotine than with analogs. I don't feel any negative health effects...yet. I've read that you are supposed to just take one puff and put it down for a while. That's defeats the whole purpose of replacing my oral fixation! I'm just curious to read what others think about this phenomenon.
