Okay, so I fill my carto with what I believe they call the condom method. But when I fill it up all the way, as instructed in a video I saw, I get a gurgling and often a bit of the e juice in my mouth. So I have been rolling up a napkin and sticking it inside to soak up the excess juice. I am wondering if there is a better way to do this. Any tricks you may use to keep from overfilling your carto while getting it as full as possible. I just feel like I am wasting juice there. Although, probably not as much as I imagine. Just wanted your ideas.
