I have a question for some of the mor experieced vapers. I just started vaping. I am pretty heavy smoker. Before I started vaping, I was about a pack a day smoker. I noticed that higher nic levels are (anything over 16-18) making me kind of sick when vaping more then 5 or 6 hits (little buzzed and sour stomach feeling). I was wondering what nic levels you guys like to use? I really need some new liquids that have under 15mgs as I am finding that I'd much rather have an analog then do any vaping with high nic levels...
