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. Talk to the doctor about trying a methylphenidate next (sounds like you maybe have if Quillivant is the next medication to try).

Definitely refrain from all citric acids within 1-2 hours of taking ADHD medication.

Here’s a lot more detail on ADHD medication:

You may consider genetic abnormalities (like MTHFR) and food sensitivities as the potential culprit for medication failure if you have the same experience with methylphenidates.
