narcolepsy
"After several back surgeries on a good deal of pain meds. Fight everyday to get out of bed. If I have a specific goal I can get up, otherwise in bed for 15 hours. After two weeks of 15 mg dextroamphetamine in the morning. I have begun to get a life back. More focused and life has become more enjoyable. Had issues with falling asleep at stop lights (3x) and nodding off mid sentence while reading. NO MORE!"
