Judy - dont worry about still smoking - I mean really jsut stop worrying about how many you're smoking and think about how many you're NOT smoking.
I didn't buy my 510 with any (and I mean ANY) intention to quit smoking.
I like smoking.
I just didn't like most of the cigarettes I consumed. Most of them tasted nasty and left my mouth feeling horrible. I had a cough, I felt stuffed up all the time and ill like I had a cold (even when I didn't). I just wanted to stop smoking the 'filler cigs' and only have the 'nice ones' - about 5 or so that I really enjoyed.
Drop your expectations and just enjoy what you're doing. I promise you that once you find your feet with your PV things will fall into place for YOU. By that I mean, you may never give up smoking, you may always have a few a day and that's ok. If thats right for YOU then its right. But once you get a good vaping routine you may find, as I did, that vaping is jsut MORE enjoyable than smoking ever was. It tastes better, it doesn't make me cough, and I dont feel all stuffed up and ill like before.
Remember I was NOT going to to quit - it just happened.
Edit: Oh and juice in the mouth - try blowing the cart out when you remove and claen the filler material. I get that even with dripping, (which is using no filler but the end cap thing becomes a mouthpiece) I think its condensed vapor + flavorings that collect inside the little cap - blowing it out works wonders
