So for the past 2 years I've been vaping and smoking normal cigarettes but up until 2 months ago I had to stop smoking cigarettes cause I was gagging everytime I took a git out of it and just thought it was cause I now for some reason think it's gross? And now not even 20 minutes ago I took a normal hit from my vuse and I gagged to the point I thought I was gonna puke. I have no clue what's going on, as this has never happened before. What's happening?
