Not sure if this will help but wheat or sugar always makes me ANGRY.
It just triggers something in me so intense I have no control over it.
Avoid it at all costs.
I still do get angry without the gluten and sugar but it's a bit more controlled and I don't totally flip out.

And because you asked ...PRAY,PRAY.PRAYand PRAY some more giving all my anger to Jesus helps. You may not be into this but this is what I had to do or else all that pent up anger turns to sickness in my body and I just can't have that, not with a family and kids.
