i stopped questioning it when i realised my brain reacts to my meds way differently than a non-adhd person would eg cant get addicted to them forget to take them feeling awful when ive accidentally double dose instead of getting high  cant fake that can i haha taking the double dose of dexamphetamine because i forgot that id taken it 15mins before on a morning i was late to work and then being woken up by my concerned partner 30mins later because it put me to sleep that was the watershed moment for me hahaha
