When I smoked my last analog on Sep.11th, that was the same day that my raspy breathing ended. It is hard for me to believe that one day on vaping pg instead of smoking could totally clear up my breathing after 40+ years at 2 packs a day (most of that time), but it happened. It was so bad that I had to find a certain position at night to sleep without the raspiness. It hasn't happened one time since I started vaping. I am starting to wonder if pg might have some additional benefits. PG is a mild disinfectant. Is there a chance that it might be controlling the viral infections at the same time it delivers the nicotine? I have never gone this far into the flu season without some type of bug. My wife even caught a virus that the doctor treated and I didn't get it (that's never happened before). It may be just luck, but I really don't believe in luck or coincidences. Has anyone else noticed that they are not getting the chest colds or crud that people around them are getting?
