I know a lady who runs a hospital pharmacy. She was telling me that one of her employees has narcolepsy, and about the accomodations they made. It wasn't even that much - supervisors asking the employee if they needed to get up and walk around, and not being surprised if the worker was asleep at their desk.

It's also, if I understand correctly, kind of legally required that they make "reasonable" accomodations. This sounded pretty reasonable to me - they didn't even have to buy any equipment.
