Are you direct dripping right onto your atomizer and vaping with a blank cartridge? Or, using a drip-tip? I'd try removing the atomizer from the battery and giving it a gentle blow (I blow mine out from the battery end, others blow out from the cart end) onto a paper towel. It could be it's just a bit flooded.
If you are using a blank cartridge it could be that some juice is trapped inside the tip of the cartridge. You can try inserting a paper clip into the opening and gently popping off the tip. Once removed, you can clean the inside of that part of the cart with a Q-tip, or rinse the entire cart and dry it with Q-tips.
I vape pretty hard, and I drip. I used to use a blank cartridge and drip directly onto to atomizer. I don't know how it would happen but on occasion I'd find juice trapped behind the little section of the cartridge where you inhale from.
I recently came back from a cig-relapse and discovered the acrylic drip tips. If I'm sloppy I'll sometimes drip into the tip a little wonky and get a bit of juice in my mouth. The fix for me to that problem is now I'll drip into the tip and give it a couple of quick flicks, or a gentle blow right into the tip to encourage any juice inside the tip to move on down to the atomizer.
Hope that helped a little!
