Opiates are known to cause rage. Mixing them potentiates the effect in a bad way for you. Just because you are a different type doesn't mean you don't have the same issue. I'd skip the middle man and go to NA or AA but if you want to swing by a Psychologist or Psychiatrist on the way that's your choice. I really hope you do get help........snip........I'm thinking maybe some professional help.
Or just step away from everything but pot Gioua stood by me coming off 22 years of Morphine. I am a chronic pain pt. Fractured my spine in a few places. Best thing I ever did was start using pot again.
