Origin of "Wake up and Smell the Coffee"

Is it always with the "and" or could it be this way:
Wake up.
Smell the Coffee.
If the 2nd is also correct, does it imply that it is definitely "coffee" we are referring to rather than a preoccupation?

I've never hear this expression nor has anybody else I've consulted. It would therefore seem it has limited distribution and may have started life as a meaningless joke or jest.
