I liked the point about assessing your emotional state to determine why you have the urge to procrastinate. I've read before that four important addiction triggers can be represented by the acronym H.A.L.T. -- Hungry, Angry, Lonely, Tired. I think these states are also useful in tracking procrastination. If you can determine that one of them is true for you at the moment of procrastination, then a break to remedy whatever it is may help.
