Sounds like it may be too high a dose or the wrong medication for you. 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. With that in mind, you may do better on a methylphenidate.
