I'm not sure why a doctor would prescribe Valium to someone with narcolepsy - stimulants like Adderall can often leave someone feeling strung out, burnt out, and even more tired in the long run... versus something like Provigil (aka modafinil) which is non-narcotic and promotes awareness and wakefulness.
