Molecular imaging studies have found that there is a correlation between low dopamine levels and aggression.
You are still early in the recovery stage, it takes a while for the dopamine machinery to get up and running.
In addition,if I recall correctly, dopamine is recycled more efficiently during our waking hours.

So unless you had anger issues before stimulant abuse, I'd give it some more time before I'd invest in padding the walls.
I would, however, warn friends and family to steer clear in the waking hours.
