evthelegend Facial flushing is very common. Not sure why, but there are tons of things that should be pursued here. It would be helpful if people created clusters of similar symptoms so it is easier to separate what is happening to people.
In my view there are lots of overlap with migraine, epilepsy and "kindling" effects in the brain for most people here. Things that decrease the threshold for ending up with some kind of hyperexcitability, often because some type of compound is lacking or in excess. It could be restricted blood flow / oxygen, running out of glucose, og some electrolyte imbalance (dehydration / overhydration). Combined with some type of visual problem that makes the brain work harder while using shitty screens. At a certain threshold things catch fire and you get the typical migraine symptoms or similar.
First see if you can mitigate the effect next time with some sugar, water, table salt and neck stretches. Or electrolyte mix if you got that available.
Disassociation can be connected to the NMDA receptors, and can be the secondary result of an glutaminergic overload. If it happens more with chinese food and Pepsi Max you might want to look into it. Provided you're not on medications that affect it.
Citicholine can also be an effective remedy if the brain fog is a result of a caffeine crash and brain strain. Provided the symptoms are related to acethylcholine. It's always worth a try as the effect can be remarkable.
