Stimulants typically have this affect so maybe consider non-stimulants like Wellbutrin. As a disclaimer I’ve never tried non-stimulants before though. And ngl my Vyvanse and in the past my Adderall give me the opposite effect and make me ravenously hungry instead, but I don’t think that’s common. And it’s better when I eat first
i gave up on adhd meds so long ago so i’m sorry that i don’t remember more but for me, vyvanse suppressed my appetite for a while (a month or two maybe??) but then stopped and my appetite went back to normal. that was the only drug i took that i noticed appetite suppression with, but i also couldn’t tell you what i took before vyvanse other than that ik they weren’t stimulants
