I've actually found a trick against this!

1. Pick a "must get out of bed before this" time. For me it's 9am.
2. Pick a time 2-3 hours before that. For me, best was 6:30am
3. Set up alarms evenly spaced, at least 10 minutes apart. Ideally the spacing should reduce as you get closer to the "must be out of bed before this" time. E.g. for me, it's 6:30, 6:45, 7:00, 7:15, 7:30, 7:45, 8:00, 8:15, 8:30, 8:40, 8:50, 8:55 and finally 9:00
4. Go to bed and be asleep at least 6 hours prior to the first alarm. I often can't do this but I try.
5. Once the alarm wakes you, take a moment to assert just how tired and shite you feel, and if you don't, time to get out of bed.
6. If you're still feeling like a piece of week old dogshit that got put through a full washer and dryer cycle, go back to sleep(ish), nap, or just rest with your eyes closed.
7. Rinse and repeat steps 6 and 7 until you feel optimal or need to get out of bed.

In a few days your body realises that while it is waking early, it also has an opportunity to rest to the optimal point, and said optimal point will start appearing. For me that's usually between 7:45 and 8:30.

There's a number of apps that promise to find this sleep sweet spot, but in my experience they're quite hit and miss. This method though has been super precise for me.
