About 6 months in my taste buds all went crazy and nothing tasted good at all.... harsh, too strong, etc. Had probably 75 flavors I had accumulated, about 10 of which had at one time or another been my favorite.....
So I got me some straight VG and vaped that for awhile.
I am coming up on 2 years and now I have 3 Halo menthols, BWB menthol, Casablanca, Bees Knees, Boba's Bounty and the straight VG that I randomly rotate, all in the same tank.... just refill with whatever I pick up at the moment.....
I seem to be more interested in the cloud of vapor to simulate smoking than TH, don't even always inhale......
Good luck with your quest........
