My favorite author, the late Louis Lamour, called that coffee where you throw the grounds in with the water "cowboy coffee".  
I love coffee, but can't stand caffeine.  I've been drinking decaf coffee and tea for years.  I drink about 10-12 cups of decaf daily, black.
At work, we get some from the coffee service in little packets thats really good.  At home I drink Folgers - not quite as good, but I learned it keeps better in the fridge.
If i drank a cup at night I would be wide awake all night.
