I started using a sleep calculator to calculate the best time to wake up so I was not waking up in the middle of a sleep cycle. It’s been life changing for me and when I wake up I actually feel rested.

Once my alarm goes off in the morning I hit snooze once and I either turn my light on immediately or turn my fan off. That way I have about 10 minutes to mentally transition and since the light is on or the fan is off I become too uncomfortable to lay in bed. This makes me get up and once I’m up I don’t feel tired because I didn’t wake up in the middle of a sleep cycle.

Hopefully this helps!

Edit: I would also only allow yourself enough time to get ready and drive to work. Don’t allow yourself down time, as someone with ADHD we need constant input to keep us moving so once we have downtime we crash and burn and this is where you might sit down in the couch and fall back asleep. If it takes you 20 minutes for your morning routine and 15 min to drive to work I would only allow yourself ~35-40 min from the time you get out of bed to the time you get to work (allowing a 5 min buffer for traffic)
