You know you're drinking too much coffee when:
 
 

You answer the door before people knock.
 
 
 

You ski uphill.
 
 
 
 

You name your cats "Cream" and "Sugar"
 
 
 
 

You don't get mad, you get steamed.
 
 
 
 
 
 

You haven't blinked since the last lunar eclipse.
 
 
 
 
 

You can outlast the Energizer Bunny.
