You’re correct. 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 3 meds you listed are all amphetamine-type. I would talk with your doctor about trying a methylphenidate. Then you’ll be able to compare and know which type works better for you.
