Map your peak window (schedule hard tasks to your chronotype)
Instead of 'wake up earlier', map when across the 24h you're genuinely at your best (ADHD often has a delayed phase / night-owl pattern) and put your most important tasks in that window — even if it's counterintuitive. Not sure when? Track your energy for a few days or ask a loved one.

A delayed circadian phase means your optimal functioning is shifted by a few hours; forcing an early wake-up doesn’t add energy, it drains it. Matching demanding tasks to your peak window maximises how much executive function you have available.
Concretely: (1) for a few days, note when you think most clearly and when you’re a fog (if you can’t tell, ask a close person who observes you); (2) put your most important, ‘brain-heavy’ tasks and key meetings in that window; (3) avoid forcing hard things into hours where nothing will come of them anyway.
It’s counterintuitive against the cult of early rising, but for a delayed-phase brain, fighting your chronotype is pure waste.
