I was getting worried because I like vaping alot and I was getting some mouth and nose irritation. I like it so much that I haven't even thought about an analog since I started. Anyway, I kept vaping and today I have no problems/irritation. Yay! I was thinking yesterday that maybe my body just didn't agree with vaping. I think that my body just had to get used to the different delivery of nicotine. Perhaps I over did it the first couple of days because I liked it so much. It's glad to know that I can continue on my vaping journey.
