Lorazepam
"Recently I started experiencing panic attacks for no apparent reason.  I stopped taking caffeine, still had the panic attacks.  I don't drink alcohol so no need to stop that.  Stopped smoking, still panic attacks.  Stopped pretty much everything I could think of that triggered these attacks.  Still had that horrible death feeling that all of us who suffer with Panic Disorder experience.  Even hearing the words Panic Disorder from my doc... it was a sobering experience.  My GP prescribed me .5mg Ativan taken as needed and they are life savers.  Within 10-15 minutes I begin feeling normal.  I can function again.  I can WORK again.  I don't know how I'd survive without these little helpers"
