Curious, what is a good sign that your nic level on your juice is too high? I have been vaping some (....ty) juice in a Vivi Nova ghettoed onto a Blu battery (sucks) until the postal aervice decides I need my Ego and Protank 2. Most is weighing in at 24 mg, with one at 18 and another at 16, all sweet / fruit vapes. I cough on most decent sized hits, and the vape seems pretty hard to me. I was thinking it could be a combo of the nic, crappy tank, and more than crappy power source resulting in harsh hits and possibly inhaling unvapes juice. Does this logic seem sound? I am hunting for 12mg juice locally (Nebraska, no shops), and I am an under a POD smoker currently on Camel menthol silvers, if that helps narrow down the issue. Ratios are 50/50 and 80/20, with one unknown.
