Maybe it's my body clock, but in the last few years I've been waking up between 4 and 6 am every morning no matter what time I go to sleep. The secret is to try to close my eyes at no later than 11 pm, but with one thing and another, it never works out like that so I sometimes end up with only about four hours sleep.
I need at least seven hours in order to function normally. If I don't get that, my battery meter reads about 45% charge and my brain starts to slow to a crawl and my eyes begin to shut.
Recently I've been waking up at 5 am and then going back to bed at 8, a quick sleep (deep) for an hour or so and then when I wake up my battery meter is back up to around 90%.
If I have a drink before bed, I sleep much better. and it's not related to quarantine at all. This has been happening for ages.
Anyone else having sleep problems?
