So i literally just filled my cartomizer with some new juice, and i was vaping it, but it was gargling a bit. I don't know if i overfilled it or if a cartomizer needs some time to completely soak up the juice before one should try vaping it (can someone clarify this for me?). anyway, as i was vaping, i kinda felt a shock kind of feeling on my tongue. It may have been some of the now-hot juice shooting out of the mouthpiece of the carto, but im just curious as to what i did. any answers?
