narcolepsy
"I have used Adderall XR for almost 5 years for narcolepsy, and find it to be most satisfactory. I still fall asleep on occasion, but feel the need ahead of time, and can take a quick nap, and wake fully refreshed. Adderall improved my libido, but contributed to ED problems due to blood vessel constriction, resulting in the need for daily Cialis, which keeps everything in balance."
