I just got my bottle of liquid today, the one I ordered for the photos I posted. Wow! So I'm vaping the chocolate carto, so I can refill it. I think it's crazy that this is my favorite flavor. It seems so -- I don't know -- unsophisticated. But I really like chocolate! So surprising. Anyway, now I wonder how I'll know it's time to drip some more liquid into my chocolate carto before I vape it dry. I know if it tastes burnt, I've gone too far, but I'd like to know some sign to stop before that. Or do you just keep dripping a little in to keep it going, whether it's running out or not?
