Have you tried exercise?
I had a raging temper for many years after I sobered up and I can't tell you how much it helped me to join a hardcore gym and lifting weights!
It's one of natures best medicine for relieving and even preventing physical as well as mental health problems.
All that rage and anger I had was much lessened after a good, strong weightlifting session.
Or doing cardio on one day and weights on another is also very beneficial for clearing your mind and washing that rage and anger right out of your system.
It's one of the reasons why so many people are addicted to the gym! If they didn't work out they'd feel like killing someone or would be angry and depressed all the time!
