It could be that your son just can’t tolerate the short-acting version of stimulant medications. They get the medication all at once and then crash. My son did terrible on short-acting pills, but does great on time-release, long-acting pills. He takes Concerta, but Quillivant, Vyvanse, Adderall, Evekeo, etc. are all long-acting medications. The time release in the Concerta, Quillivant, and Vyvanse are the smoothest from what I hear.
