I have TERRIBLE anxiety from GAD and PTSD. There is a law in AZ that a dentist cannot give "laughing gas" and a benzo together. I HAVE to have the laughing gas, so I called  my PCP for something to take the night before and the morning of and he gave me visteril/hydroxyzine. I have never taken thisone, only valium, Ativan or Xanax.

I just want to make sure I don't flip out on the table during my root canal.
