Maybe it's the sugar that does it. As a candy, the sugar to coffee ratio is WAY higher than any coffee cup I've ever seen.
Sugar is a game-changer, and for me, with enough of it, I can tolerate even most flavors I don't like naturally (grapefruit, alcohol, sour candy, etc.)
And seeing as it's highly addictive, it's no wonder they add it to absolutely everything, including salty things like chips and French fries.
I have actually prayed many time that God would take away my taste for sugar, except for in healthy things like fruit.
I get a kick out of false advertising for things like fruit snacks that will say they're "made with real fruit" -- sure -- if one mashed strawberry in a cup of sugar counts.
