Hey all! Need some help. Vaped 36mg for 4 years. Used to use high PG, but for the last year I have done all VG. The PG started making my lungs feel like they were collapsing. Over the last month, I have developed a cough. Every hit I cough. If I smoke an analog (an occasional one over the last month), no cough. No vaping, no coughing. Went from cotton wick, to silica, to SS wick. SS makes me cough a little less, but not much. I don't think a VG sensitivity would take a year to manifest, but then again, it took PG like two years to manifest issues. I use tobacco flavors (flavourart) at 4-7%. Currently still on the ViVi Nova and Provari (AGA T2+'s ordered). Any ideas would be appreciated!
