Important to remember too that an addiction to an opioid like Norco will alter your brain chemistry, especially the areas and chemicals that regulate mood and emotion. So some of the anger may be like the brain effects of withdrawal. It always helped me to realize these effects after stopping drinking. Good thing is, your brain should start to correct itself, and you can talk to your doctor if it's really bad. Exercise, sleep, good diet, low stress and above all compassion for yourself is important while your mind heals.
