I had that exact same problem, and I found out it was related to the resistance (ohms) of the clearomizer. lower ohms (1.8-2.4) were way harsher on my through, but a higher resistance (2.8 ohms) totally took care of this problem. hope that helps 
Just looked at the Johnson Creek website and their juices are all 100% VG -- this is a good thing right?
This is what I just purchased from JC.
Johnson Creek Original Sample Pack Johnson Creek Smoke Juice
Are all of these 100% VG?
If so can you buy PG separately (like you can with VG) to dilute the juice with?
Or should I just dilute it with my 75/25 PG/VG juice?
I have been vaping without inhaling in order to keep smoking even though it is harsh. The flavor is moderate but even though I am not inhaling the vapor is leaving a strong, unpleasant tingle on the back of my tongue / roof of my mouth (like an uncomfortable tingle leaving 3.5/10 discomfort for ~3-5 minutes) *even though I am not inhaling*
Is this symptomatic of something? Is this how all 18mg Nic vapors are?(Keeping in mind that the Blu I was smoking was using 18mg Nic and didnt leave any sort of tingle even though I was getting Nic)
I hadn't until this point vape'd without inhaling and I am finding it irritates regardless.
Thoughts?
awesome thanks all - I have the JC sample pack coming and a bottle of 100% VG 1.1mg Juice also on the way. I am also going to buy some 2.4 ohms heads and hopefully have better results after trying some different configurations.
I also think the Vivi Nova I got was a knockoff, the heads don't look like any of the "vision" brand heads-- if I still dont have good results i'm going to buy a real vision vivi nova mini off the internet and hope for the best.
Determined to get something I love!
