Taking vitamins and washing them down with coffee: It seems kinda counter-intuitive.
But it is good coffee.
"Coffee is the second most traded commodity in the world, trailing only petroleum. Coffee is one of humanity's chief sources of caffeine, a stimulant. Its potential benefits and hazards have been, and continue to be, widely studied and discussed." - Wikipedia.
I think that life withoutcaffeine isn't worth it. That awake, alert feeling is unbeatable. And after you've had coffee for a few months, it's hard to go back. It's an addictive drug. Without it you'll go through withdrawls, feeling exhausted and having a tremendous migraine. So it's just too easy to keep drinking, more and more.
