I can't say I'm quite as a bad as you are describing, but I do know when I have low electrolytes I don't function as clearly. My energy responds way better to salt water, keto lemon aid, and pickle juice way better than caffeine in my coffee.

Have you had a sleep study? Maybe you are not sleeping as well as you think you are.

I had those same symptoms on a prior attempted at LCHF. The brain fog was real. I found that drinking a cup of chicken broth with a tbsp of salted butter and taking a magnesium supplement daily cleared it all up. I now also drink pickle juice on a regular basis (which contains sodium, magnesium, and potassium).

I also have had various sleep problems. Condensed version - blue light filter on phone. Dark cold room to sleep. Sleep tracker with "SleepTime" app on my phone that wakes me in a 30 minute window to find my lightest sleep. 5-htp with co-factors to aid sleep (offset by tyrosine during daytime). Routine. Making sure I get daylight early as possible (with D3/K2), then again at 12-2 pm to help with natural circadian rhythms and natural cortisol lowering and melatonin increasing...

I take 800 mg magnesium daily, 400 am, 400 pm. I still have occasional signs of deficiency...especially after lower water days, higher activity days, or just humid/hot/sweaty days (No AC in my car, etc.).

I'm not on much on the weekends, but I'll make a note to hit back this thread if there are questions. Otherwise, hit me up on PM and I'll check that, too. (Sorry for the short version, but have an appointment - if I need to explain any of the above, please holler.)

Above all, remember that there is often a huge difference between acceptable lab ranges in bloodwork and the optimal ranges where we actually feel our best! For example, most labs say TSH can go up to 4 or even 6!!!! Optimal range for 95% of people is 0.5-1.5.... So yeah, major differences. I had a doctor who told me that at 4.7, he didn't understand why my PCP had even medicated me...yet my TSH cut in HALF... Seriously?

Well, at least I can rule out gluten or other carb sources as being the cause of the brain fog I've been experiencing for years. Keto has not helped that one bit. Anyone else experience this? I'm just groggy, forgetful, lacking focus. It's like that just woke up feeling, but lasts all day long, even after a double espresso. I work out, get okay sleep (occasional insomnia which of course makes it worse), have decent energy levels, no more stress than the next guy, just evasive sense of mental clarity. Maybe it's just getting old (51 now).

I was going through this for years beginning in young adulthood, tired all the time, sometimes loss of appetite or over appetite, fits of insomnia. I got my bloodwork done to check for thyroid or vitamin D deficiency...blood work came back fine. Dr. suggested I see someone for Depression. I met with someone, and was diagnosed with Major Depressive Disorder when I was 23. I have been on meds since, and they have helped me. I am not saying this is what it is, but it is something to consider.

Hey, just a small note here, go see a neurologist. I was having micro-seizures with the same symptoms.
