Wanting to give my lungs a break after 38 years of heavy smoking, and now constant vaping. My chest really needs a break from inhaling in general 7 days a week for 38 years. Wondered if anybody has tried this AFTER taking up vaping to catch a break from inhaling? (yes I think most of us have tried some kind of NRT whilst trying to give up the fags...) Anybody tried this recently and how was it?...
