Not sure I agree that calming down is that great. The mental/physical excitement (by which I mean an "accelerated state," not that one is "excited" just gets suppressed.
I had some difficulties and would do sprint work, long farmer carries, or things like 10 sets of 10 of 225lb squats, mixing in dumbbell bench, sled, or overhead press. Had to burn out the adrenaline and make my mind and body tired.
Also booze/pot and really bad choices with women to create drama that was not the same drama one is dwelling on is rather useful, although more risky.
