Dosing schedules for ADHD medications like Adderall and Vyvanse have shifted from weekdays-only to including weekends.

“One thing that's being explored quite extensively now in the treatment of ADHD are drug schedules. Whether or not people should take Adderall every day or every other day, whether or not they should take it only every once in a while, whether or not young children can take it just a few times and engage in behavioral training of the sort that I talked about before, where they're doing, maybe it's a 17 minute meditation type exercise, but more likely it would be the movement followed by the visual focusing, cause that's only done for 20 or 30 or 60 seconds.”
