Suggest Remedy For A Hormonal Problem

have always had real aggression issues all my life, i try so hard these days to keep a cap on my temper. today there was a situation where a guy had a go at my wife being real nasty and generally a nob, it almost nearly into a fight between him and me. i managed to keep my temper and rise above it all but my problem is that when i get angry my body seems to get ready for war and dumps huge amounts of adrenaline into my system (its like rocket fuel to me), so much so i get the shakes. now after the confrontation i was left with all this adrenaline floating around my body and it has left me feeling very depressed i m really kicking myself for being the bigger man and constantly playing through the event in my mind. i just woke up having had dreams about it. i don t want to feel like this again if i have to rise above situations in the future. so my question is this how do i control my bodies natural reactions to confrontation? if there is no real way to control it how do i get rid of this crappy feeling it leaves me with?
