My sister has narcolepsy. She takes Adderall 30mg three times a day. She has worked up to this dose over years, as the lower dose loses its effectiveness.

My nephew gets extremely sleepy on Adderall, it's like giving him a sleeping pill. Ritalin works better for his ADD.

Stick with the lower dose for a while before increasing, and if you don't find a marked improvement then tell pdoc to keep her in the loop, and try a different med.

Good luck!
