You’re doing everything right in terms of sleep hygiene, and I assume you have a regular sleep/wake time, but your body has got into a rhythm.
I would suggest going to bed an hour later than usual for a few days, then increase that to 1.5/2 hours later for a few more days, and see if that breaks the pattern. You can then creep the time back again once the cycle has broken.
Thank you, appreciate the advice and will give it a go. Understand that
Could you put together a good sleep stack and where to purchase from. I go to sleep ok but wake at 2am and can’t get back to sleep. Already take dream sleep and no screen time etc pre bed
