Hello Lori,
Xanax is a very good drug for panic. I've been taking meds on/off since October 2006 (before that I used to take my friend's tranquilizers).
I guess panic related to narcolepsy would have something to do with waking up. I'm no neurologist though, nor have I studied narcolepsy much, but just a guess

Did you suspect narcolepsy before you got the diagnosis?
I'm not sure if perphenazine is helping much, I'm still paranoid, I think I'm seeing things and stuff like that..
But it's better than taking Risperdal or Seroquel (at the antipsychotic dose - I sleep 12+ hours a day at doses higher than 100 mg).
I'll keep taking this just in case :]
