Adult diagnosed forty years person here. Basically this is my experience, can add to these excellent tips to provide yourself with a lagom, level headed amount of stimuli, you research what is correct for you, it may be jungle rain, iron works sounds, sped up techno with echo, but don’t be a problem and make it excessive or extravagant just use it for its purpose and don’t make it your identity to be eccentric, just find the frequencies that tune fork vibes your brain activates from and use it.
