The recipe comes from this one.
e-liquid-recipes.com/recipe/36098/Vanilla%20Coke

and i saw somewhere else that people add some strawberry flavors to make it less boring...
well i'm not looking that sweetness and just want a coke base, i choose the grapefruit to make it less freshing with that bitness flavor.

the menthol is optional (and i didn't make it but i think some eucalyptus will be nice,too)

now i quit smoking and i cut the coke off too with this new ADV.
