so i vape only 100% VG juices. Virgin Vapors, dekang, AVE, copper creek. I do drink alot of water and stay at 18mg nicotine. Ive also been vaping for a year but quit off and on. so now ive been off the analogs for 3 weeks and have been steady vaping. the problem is, when i vape, i get this gritty , sand paper feeling on my teeth, just like if you ate raw lemons, or had a lot of viniger. I notice my teeth dont feel smooth after vaping( by slightly rubing my teeth together i can tell). its super annoying. Has anyone else had this problem and what did you do?
