Already done, mixed about 18 differents eliquids, some in 6mg, 12mg, 18mg, fruity and tobacco flavors, all that I didn't like but didn't wanted to waste, got around 150ml or so of it, was pretty good actually, vaped it for like 2 months but that was back then when I was vaping old burned cartomizers, I just wanted a throat hit I guess, didn't cared for the taste, now I'm using fresh atomizers and DIY eliquid, I need a good taste.
I mixed a few ml's of menthol in it at the end, just a few, and it killed all the flavor with menthol, that thing is darn strong, don't mix menthol in anything if you don't like menthol !
