Any of your Berries or Lemonade I have even put a couple of drops in my Mountain Dew lol. I don't buy much store or on line flavors I prefer to make my own. Sometimes I will add a drop or two to my tank just to see lol. Again be careful Too much Too soon and it will take your breath away.
Yeah, I find this especially true in the morning when I first get up, since I like the Koolada to be fairly powerful; fortunately, my variable mods can help me handle it very well, just by turning down the power a bit -- even the koolada is more pronounced at higher power, and less so at lower power.
I was thinking of getting some of the Killer-Juice Juicy Fruit, now I've learned that KJ's juices are 40%PG/60%VG, and adding some Koolada to that -- I always loved that gum, but wished it had a "cooler" sort of taste.
So far I haven't been too successful with the DIY thing, but I keep trying, not really knowing for sure if the problem is the flavor brand, the flavor percentage, or the steep time. I guess I'll sort it out eventually, but meantime I'm glad I got some Koolada, to add to other flavors I like but would like to be cooler.
