For all you douchebags who think its funny, its actually possible. You can get hooked on the caffeine in Coca-cola, not the drink itself.
Of course, you don't have withdrawal symptoms if you stop drinking coke all out, but you might get a bit crabby. It's not that much of a real addiction either, there is just enough to make you compelled to drink another.
Or it might just be habit, after all Coke is delicious
