Welcome
@BluVap0r
I notice you are not vaping BLU.... (the brand) which is excellent news.
(Clap along if you feel like happiness is the truth....

)
I am not surprised you are coughing. I coughed using "Supermarkt" e-cigarettes.
Then I coughed using a Kanger eGo e-cig.
I was still coughing a month later.... but I persevered.
e-cigs might be a miracle, but vaping does take some getting used to.
