We are one of the minority who saw self-harm talk when a certain medication was a bad fit. There are two types of stimulants: amphetamine (Adderall, Vyvanse, Evekeo…) and methylphenidate (Ritalin, Concerta, Quillivant…). Almost everyone does well on one type or the other, but not both. You son might need an amphetamine. Or he might not be able to tolerate stimulants. Or his dose of Quillichew could be too high for him.
Talk with his doctor about making a change ASAP.
