FAA, when I got my first Buzz I was vaping 18mg too and had the same over nic'd problem. Dropped to 12mg and have been there for over a year now. The higher voltage packs a bigger punch. Also remember to check your cartos more often for topping off since you'll be going thru a little more juice. The tanks are awesome and I highly recommend them!
Sad to say that the only dealings I have had with the FAA (not really dealings since I was just 5 years old) was when my Dad crashed his Piper and died in 1965. I still have the FAA report packet and pictures from the scene.
Sorry to hear that
Back on happier topics... I have definately gone up to about 6 ml a day, and the only reason Im not at 10ml is too much nic... I have never felt a nic "buzz" (pardon the pun) like that.
I want to move up to a tank as refilling cartos every hour or two is a PITA.... But I dont think I have found that "LOVE IT" juice yet. The juice I did like with my e-cig is WAY too sweet with my VV at around 4.2-4.5 v, but if I go lower then there isnt enough vape to make me happy... (oh so hard to please...those darn VV users... heh heh)
Im looking for something fruity... something that gives you just a hint on the way down, and a nice finish on the exhale. Most of my juices now make me feel like I ate a Jolly Rancher (hard candy for anyonone not familiar).... They taste good..but not for an all day vape.
I will also try 12mg, hope that does the trick as I love to sit watching a movie and chain vape...the more billowing clouds around me the closer I am to angels
