Hey guys. Been vaping for 10 months now. Got into DIY juice. Got some advice on here and tried 70/30 pg vg to combat shortness of breath. It only got worse. I 've been dripping and gone through about 20 ml of juice a day for 5 months at a minimum of 35 watts with direct lung hits. I think that much vaping has taken it's toll on my chest. Does anybody know how long this tootle puffing will take before I can stroll down the street without breaking into a sweat, and then lying down when I get indoors? Anybody else?
