Well hey guys, I just started vaping last week. Got two orders of ejuices in. First batch was a sample pack of 50/50. After the first day of smoking the 50/50, my throat had a really scratchy feeling and I was in constant thirst. I was really annoying with this feeling and stopped vapping for 2 days. Throat became back to normal and started vaping ave 100% VG juices and the feeling I had few days earlier stopped? Is there a for sure way, to tell if i am sensitive to PG? Thanks for your input!
