OK so I started vaping around 2-3 weeks ago and have since been having fun learning the experience and just having fun with it. Recently it seems that i have developed a problem where it seems like i can't hold the vapor in my lungs without it making me want to cough. Whenever i go to inhale my lungs just don't seem to want to have a clean smooth inhale and it often makes me want to cough. I don't really know what to do and any help would be appreciated.
