I started with 80/20 PG/VG, my nose literally ran so much I needed to carry a kleenex tissue. Back then, also needed the tissue cause all my tanks leaked. Last several months I've been using 50/50. Nose drips occassionally, but not bad. And it takes about a week before the insides of my car windows become so clouded with film that I need to clean the insides. When I used 100 VG I had to clean windows daily. The VG really clouds up the insides of auto windows, even cracking the drivers window. I evidently have some allergy to the PG, but at 50/50 It's tolerable. I suck on my ProVari continuously when not at work. Haven't touched tobacco for more than a year. I'm not your average ecig user. I stopped using flavor and nicotine 6 months ago. All I blend is the two base chemicals, PG/VG, 50/50. It's all the oral gratification to me now. Heavy VG really dehydrates me, even my hands dry out. I drink water as much as I can, guess it helps, but still dehydrated. JMHO
