Painter, I struggle with anger too. One thing that has helped me is I just allow myself to "feel it" and after a certain period of time, 15 minutes maybe 20, and then I decide "I didn't deserve to be lied to/cheated on/spewed at/gossiped about, etc, I am worth so much more than this. " And then I will do something nice for myself, for example, watch a show, or take a walk, or play some fun music or have a piece of chocolate (have to reign that one in.) So I experience the anger, and then nurture myself in some way, big or small. I am learning to be nice to myself.
I feel flashes of anger every day. Every single day. And sadness. At least the anger is "activating" if that makes sense. I think if you can manage it and not be consumed it can be a helpful emotion.
Fo, I love your approach! Time limiting is good. I find the anger tends to grow and spread out, and cutting it off would be a first good step.
