Basically, if coffee and its own anti-coffee collide, it is as though they cancel one another out. They destroy one another and turn into a flash of pure energy which can manifest itself as light. This flash can be more effective than coffee, because 'eye burn' caused by flicking on the light after you wake up is immediate, just like the pain from quickly ripping off a band-aid. One side effect is spotty vision for two hours, but as long as you shave with an electric razor, walk to work, and don't ask any 'people' for a date, you should avoid embarrassment.
