anxiety
"Had this in a "headache cocktail"  last night when I went into ER for an intense migraine with garbled speech.  NEVER again.  I have never appreciated a headache more because by comparison it was so much better than the side effects of Compazine. It made me a crazy person in full blown panic attack mode.  I was trying to pull out the IV and run away.  I felt doom and dread and mental anguish.  I was yelling and just trying to figure out a way to kill myself (literally) if the mental pain and confusion didn't stop soon. Luckily the terror didn't last long because three nurses came in and gave me more benedryl which counteracted or at least knocked me out. I am a bit traumatized by the experience but feel alot better today."
