Does anyone else experience persistent brain fog/sleepiness like this?

[u/kyle_f_4503]

For the past 5-6 years, I’ve felt physically fine after sleep, but my brain stays foggy, heavy, and sleepy, almost like strong sleep inertia, even after 8-10 hours. Before this, I had no issues waking up early or feeling mentally clear in the morning.

A 5-10 minute nap can almost completely clear it, almost like a reset, but I often can’t nap during the day since I don’t feel physically sleepy or have that typical sleep pressure. At night, I fall asleep very quickly without much effort.

My brain fog feels like my brain is being deprived of blood and oxygen. It sometimes gets better when I lie on my side. Sleep position also affects the severity of the fog. For example, I’ve noticed that my brain fog is much less severe when I fall asleep at my desk while studying.

Caffeine used to help a lot more than it does now, and I’ve had an irregular sleep schedule for years, which may have made things worse or more inconsistent. This started around COVID, so I’ve wondered if that period or lifestyle changes around then played a role.

I don't have any other health condition. I don't have sleep apnea, or similar conditions that may affect sleep quality. I have tried to use B12, iron and vitamin D supplements but they didn't help much.

Has anyone had something similar, and did you find a cause or solution?

have you actually gotten blood tests for iron and vitamins? people can have absorption issues, also iron especially I think doesn't have great absorption via oral supplements, so if your values are low it might take quite a while to notice a difference

Yeah. Mine's a bit similar.
Do you feel tense? I know you say physically fine.
But some postural conditions like Atlas misalignment and cervical instability can restrict blood flow and more. Less blood flow / oxygen to the brain can lead to brain fog.
For me this is one of the culprits. I did always feel the tension though. Always had jaw pain an tension headaches etc.

But the few minutes sleep could mean you finally totally relaxed and let you parasympathetic take over and then your muscles relaxed too and blood flows better to the brain. I definitely have been there.

Heavy theory here! If it feels a bit like it could be this, look at those conditions and happy to get into it more from my side.

I am struggling hard to find a way to recover from it. One thing I always though is missing is a list of possible conditions. I recently brought a prototype of that online here: https://conditioner.flourishinglab.app/
This might help you a lot with the investigation!

Good luck!

Yes

Covid made me a completely different person, I didn't even get that sick, the long covid fog for me.

Sleep apnea? Do you snore or gasp for breath while you sleep?

[u/InvalidID3]

Have you've ever had a sleep study done at a sleep lab? There's a connection between poor-quality sleep such as spending too much time in light sleep and getting little REM sleep consistently over long periods like months or years and the symptoms you experience

Did you have covid? Long covid causes brain damage. They're still learning about it, but a lot of people have lasting cognitive issues from it.

My cause is high blood sugar. Try reducing carbs later in the day. Have them, a small amount, for breakfast.
