I had read something about ecigs back in 2009, and went online and got me a white cloud system. I liked it but coughed a lot. Like many here who first started vaping, I had thought it was the vaping but it wasn't, it was my body's way to get rid of years of smoking... So I stopped, but not completely, went back and forth with analogs. Then a friend lent me his Provari to try, and no matter what I stuck it out, perhaps because I loved the taste and the vapor production, and over night, it completely took away the need for analogs. Roughly a month later of serious coughing and asthma attacks, it cleared. I used to have to nebulize 2-3x a day due to allergies (and possibly analogs), but since then, my nebulizer just collects dust. I've been in martial arts since I was five, and it has been great to be able to work out for hours without having to deal with asthma induced by exercise and having clear lungs. My best experience with vaping is with rbas 0.8 to 1.5 ohms on ss 400 mesh with various mods (both the provari ((1.5 ohms)) and mech mods with ((<1.5))).
