Stimulant medications affect each person differently. Dextroamphetamine might be “a far more inferior drug” for some, but could be just the right medication for others.
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.
The only way to know which medication is right for you is to try them.
