My vape keeps gargling and letting juice in my mouth.?

Sounds like a seal or airflow issue. Check all your o-rings and connections to make sure nothing's warped or loose. Make sure your wick is large enough to prevent juice from seeping past the wick and into the air tube. If your tank works on vacuum, make sure you're filling it in the correct manner, not taking it apart in ways that breaks the vacuum seal and lets juice seep where it shouldn't be.

Another possibility is juice thickness. If you leave your mod in a hot car or even chain vape for awhile, it can warm your juice to the point where it's thin enough to seep out where it shouldn't be. You can try using a higher VG mix, slow your vaping, and be sure never to leave it in a hot place.

That's just something that will always happen. It'll go away for a while and come back. You just need to deal with it because even if you got another new vape it would start again. It doesn't mess up the vape it's just something that happens.

If you bought it at a vape store, take it back and get them to sort it out. I got tired of messing with them and use a Vuse e-cig. But then I don't vape much.

If you're not using it to quit smoking throw it in the trash and problem solved.

Agreed, if it's not to quit smoking, then please just stop.
