I take propranolol, a beta-blocker to help when I am triggered. If I get around my dad, my BP will spike and I will have tachycardia. I found it to be a much more effective option to benzodiazepines. It is actually part of how I came to be diagnosed with PTSD. None of the other drugs worked. It is a physiological response, that triggers lots of physical symptoms. I will get them without feeling anxious.
