I used to always say, you might not know the diff drinking it, but you'll know the diff when you wake up in the morning.

Granted, looking back that's still biased, because, plot twist, when you're drinking the bottom of the barrel cheapest vodka on the shelf, you're probably college/military junior enlisted age, at some bar or house party, and all that sub cheap plastic bottle vodka you're drinking is also mixed with the cheapest sugar slush you can find too.

Was it the cheap vodka making you hung over? Or the red bull and raspberry blue slushie mix?
