I have this too. I didn't want to accept that I was a rager, but I have terrible road rage, I have made a fool of myself at the grocery store on a few occasion, and I'm no longer welcome at the post office due to my anger. (well, I'm too embarrassed to go back, not that I"m not allowed)

I don't go out when I'm in my moods. It's not safe....I'm afraid I'm going to "go off" on the wrong person someday and get myself killed. I'm serious too.

I will try the 2 breath rule.

Best of luck on finding a solution to this.
