Yeah, you probably just overfilled it. When I got my CE4 and Kanger T4 clearomizers, I filled them up past the top of the wicks, and found out that I would get juice on my lips every 5 or so hits, until the juice inside the clearo got down past the wicks.
Stupid me finally realized that I was filling them too much, and once I started filling to just up to the wicks, I haven't had that problem again.
And yes, ejuice tasts gross. I try to vape at a slight downward angle. Nothing too drastic, like straight down to the ground, but I try to not go above level to my lips, since I'm concered with it leaking.
Cheers!
