My name is Nathan and I have been vaping for a little over a year now I have not smoked a cig in my life I have smoked cigars and I did smoke hookah for a while but not enough to claim I was a smoker. So any ways I found out about vaping about a year and a half ago and I was very interested so I started vaping I loved it!! So my current set up now is my snow wolf 200w tc, and my twisted messes rda. So a few weeks ago I've noticed that I've been wheezing after I vape and I also cough after words as well its concerning me because this hasn't ever been an issue as I said I've been vaping for a year and a half now. Why is this happening now? I vape max vg and sometimes 100%vg juices. I do not like pg juices because it murders my throat and I'm sensitive to it. I vape every day and when I do vape I chain vape until I'm satisfied so on average when I juice my coils I get at least 3 to 5 good nice hits and I juice my coils at least three to four times until I'm satisfied. Sometimes when I'm doing nothing I just vape away. A 30ml of juice barely lasts me a week sometimes. Am I vaping to much ? I would appreciate some help and advice to stop the wheezing and coughing.
