I'm experiencing all that you have said in your posts - minus the spouse thing. I'm noticing it more and more and found ways to cope with it even though my coping mechanism has been lacking recently.

Whenever I feel that rage building up, I just stop. I shut up and don't say anything and take a timeout.

I have yet to visit a neuropsychologist because she hasn't returned my call for an appointment yet. I also told the person who assessed me briefly, a neurologist, that I would be against taking any medication as I'm very sensitive to it. Behaviour modification would be the way to go and "treatment" in my eyes would be staying.
