Benzo's are also highly addictive and should be used with caution. Are you able to see a therapist to work out the anger/violence/self-harm issues? The problem with them is they are quick fixes, and don't attack the underlying problem causing you to behave a certain way in the situation.

More serotonin in the blood is said to reduce violent tendencies in general. Wellbutrin is actually prescribed off label to help people stop smoking and could potentially help with the violence etc. Honestly, though, talking to your pdoc about a med change is probably best...perhaps using suggestions from the board.
