Anyone that knows me, knows that I like my coffee.  I drink it all day and into the night.  I can drink 3 or 4 cups at night and still sleep like a log.  I joke sometimes that I snort instant coffee while a wait for my mornjavaing pot to brew.  The nice thing is that most studies say coffee is good for you, with few side affects.  No calories, no sugar, no fat, just good old caffeine.  By the way, coffee must be consumed black.  Don't bastardize it with cream, sugar or any other foreign substance.  Drink it just the way nature intended, black!  Aw, yes, coffee, from the second greatest plant ever.  Drink up!
