I started CBT this week and the first thing they talk about is Healthy and Unhealthy emotions. Anger they list as an unhealthy emotion. The couterpart to this is annoyance. You can still express the way you feel but you don't have to rigid about expressing yourself in an angry state. I am dealing with anger issues as well as some others and reading that chapter really opened my eyes. I can get my point across without having to raise my voice or slam a door or two. All I need to do is realize what my trigger was and what belief it broke and understand which negative thought process was at work. I know it sounds hard to do in your head but it really works. Once you realize what is causing the anger then you can work on changing an aspect of that situation. I have done that with my driving already, I drive in the slow lane and do the speed limit (I turn up the radio so I don't hear the blaring horns behind me) doing this has really gotten rid of my road rage. I still get ANNOYED when someone does something stupid, but I don't let it ruin my drive with anger. I don't scream and cuss as much as I used to either. Hopefully this will help you. If you need to PM me for help.
