I'm looking for ease to start off with. Would it work to buy, say, 120 ml of 36mg nic in PG and mix it with 120 ml of VG would I come out with a 240 ml of 18mg 50/50 that I could then flavor as I see fit? I assume that the 18mg would fluctuate a bit with the added flavorings but I can live with a little difference. It seems right to me but I don't trust my menopausal brain...
