Have you ever gone to 7-11 to the soda fountain and put in a little of this and a little of that from each one? That's what I'm vaping today. Definitely interesting to say the least.
Whenever I dump out the last bit of juice from a tank because I want to change up the flavor, I pour it into one bottle, the same one for all -- and I call that juice "Mongrel." My husband loves it!
(I don't think you have to wait that long, but it's not a shake and vape for the full flavor)
