I have been making my own juices for a few months at around 18mg of nicotine. I made one for a friend the other day at 24mg and noticed it seemed to have a lot more punch to it and the flavor seemed a little harsher than what I am used to. I used the same percentage of flavoring and pg/vg mix. I was just wondering if I should make adjustments with flavoring with higher or lower nicotine levels or is it that I'm just not used to the stronger throat hit from the 24mg.
