I get juice in my mouth sometimes also, it sounds like your putting toooo much juice in. Sometimes I get the gurgling sound to. After a handfull of puffs the gurgling will stop and you can still get some more puffs out of it. I put AT MOST 3 drops on the bridge of the atty. Sometimes just one or two every several puffs depending on how heavy I am vaping that day. just don't get your atty too hot and you will know when to add more (no flavor, decreased vapor) and in my case (i use VG in my juices) when you hit close to the end you will get a very thick white vapor that tells me that I am almost to the end because that's the VG vapin instead of nic. You'll learn, just don't put so much and vape more in between without getting atty hot or dry. Good luck! I'm sure you'll get lots of answers to help.
