TBH, I'd be more inclined to try and address the rage rather than suppress it. The Vit B is very good for helping with stress levels for sure, but only if your levels are down or being drained through constant stress.

If its a part of your personality (as it is mine) , it can be helped. The excercise will be very beneficial, but you need to try and address the lack of balance in other ways than anti-d's or some sort of happy pill. That can be an easy way, and doing it naturally can take longer but will also serve you in the longer term.
