On April 1st 2008 two guys that worked in the same office as me replaced all the coffee with decaf all day. I felt horrible and didn't know why. I took some aspirin for the head ache but still felt awful. I yelled at people including my wife(now ex-wife) and kids. It was just a horrible day and I couldn't understand why. Hopefully that will be my last day without coffee until the day I die.
