I think 'defrag' is a perfect word for it. They say writing a list or a journal helps so no reason why offloading on Hive wouldn't help. Hubs wakes at 3 and can't sleep as his mind is whirring so when it gets bad I put a notepaper and pen by his bed and it works brilliantly.
I don't really have e issues waking up, just the 4 am cortisol rising which seems common to woman my age. Sleep has been a battle these last five years but you know what helps the most? Being out in nature with no fucking phone.
