Why does sugar free red bull make me sleepy?

[SPKrazy]

one can makes me wakey

and another can makes me sleepy

and the ones that mother gave me


didn't do anything at all

okay I'm sleepy

nappy nappy time

:boring:

:P

1. None of those energy drinks do anything for me

The sugar in some of them might give you a quick boost, but within a couple of hours you'll want to be finding a good place to take a nap. I just drink regular, old, black coffee.

2. You may be drinking the wrong

First, fill the glass with ice, next fill it 1/3 with your favorite vodka, remaining 2/3 with the sugar free red bull. Stir and enjoy! It's my favorite when shooting pool :D

3. vodka is the only thing that makes red bull drinkable

it tastes like cough syrup on its own.
