Ryan, you know we have the same issue. Personally, I just turn up some heavy ass metal and totally just go berzerk. It puts alot of stress on your body, but it calms you down and makes you a little bit stronger.

Its the perfect solution, actually. Last week, about a month after I started training again, I tried lifting weights, couldn't pull off what I had before...So I decided to just totally lose my shit. Two days later when I could walk a bit better, I realised I could lift atleast 10 lbs more, easy.

Still, if you love the feeling, this always helps, and the 'addiction' to the feeling of power you gain from anger will eventually die out as you calm yourself more and more.
