Day five and I have to admit that overall I'm not seeing much of a difference. He has been slightly better about staying dry, with fewer accidents overall. But honestly, we've seen weeks like this before. He is as distracted, restless, and echolalic as always. (And, to be fair, as charming, funny, and talented as always as well.)
His doctor told me to give it a week, then give her a report. So, two more days and then we revisit the plan.
