So a couple days ago I was vaping on some new 80% pg 20% vg juice on a new LR BOGE cartomizer with my joye 510. I noticed the throat hit was exceptionally harsh. So far I've only been vaping 50%pg 50% vg juices. While vaping the 80/20 my lungs got REALLY tight and I was having a difficult time breathing. I also noticed my sinuses felt weird. I rarely get sick and the next day I felt HORRIBLE. My sinuses, lungs and head hurt like hell and my throat was really dry. I was wondering if the high % PG caused this or if possibly the juice was too old? Obviously it could be unrelated but it seemed like there was a direct correlation with the vaping and the illness.
