Curious question. Do you guys do mouth to lung or direct lung hits? Seeing that most of us are ex-smokers, we are quite used to mouth to lung hit, but it makes me cough when I vape. Is it a common problem?

Now, I am starting to get used to direct lung hit and it feels a lot smoother. I am using a subtank mini with 0.5ohm The thing is I actually missed doing mouth to lung and have been trying to find the proper way to do it without coughing like an idiot. I tried everything like tightening the air hole but still cough. Any sifu here mind to give a few hands on how to vape the way we smoke a cigarette?
