re: How do you effectively control your temper when you find yourself getting angry?

This will be a spiritual answer so skip if you want.

The solution is not to work on your anger but to increase your self-control.
Self-control is a fruit of the Spirit from Gal. 5:22-23. It is grown in us by the Holy Spirit through our growing relationship to Him. A lot more could be shared here.

Anger is actually a needed emotion. But we are also admonished to "be angry but sin not". It's not that you are angry, but what you do in response to your anger.
