This is coming from a teenager but frankly, in my opinion:
Coffee TASTES like SHIT to me.
I've put sugar in it, I've stirred it like a professional soup-server, the only thing left is to try every different brand in existence. But I cannot MAKE it taste an better for me, I cant' seem to grasp the taste of it. I'm not going to lie, I've got a natural "adrenaline" built into my body that provides the same energy boosts that coffee does and its rare that I'm tired except for long school days and exercise, me drinking coffee is pointless.
Or maybe I've just been blatantly ignoring the pure amount of caffeine in the stuff I drink, and it just piles on top of my already high stamina.
