There are some highly experimental chemicals that float around the fringes of nutrition science, often used by bodybuilders and transhumanists who both like experimenting heavily with their bodies.
But it’s not always well regulated if at all; they may work for a few people but then for other people make them violently ill; and with no proper scientists involved in the process (they may be scientists but they’re on a company payroll unbound to academic ethics), there’s few safeguards.
Definitely brain fog. Electrolyte imbalance likely too; that gets nasty sometimes. Too much of the wrong kind of salts or not enough salt… not enough water… and odd sweeteners can certainly mess with salt levels as they often use salts in “creative” molecular ways in order to simulate sweet flavors…
I’m really glad you went into the doctors to get better.
In my late 20s/early 30s I did a lot of experimenting with different pills – all over the counter. I had some strange reactions to a few things, mostly things that were supposed to help my muscles.–
You need the right balance of salts (there’s six of them I think) in order to support the “switching functions” – the gates.
Calcium, potassium, sodium, magnesium – and two others I forget. I see them as the thing that maintains “railroad track” switches in the brain, going from thought to thought, allowing them to operate effectively and smoothly.
Sugars of course feed mitochrondria which help physical energy, although your body will happily use fat instead if it is devoid of sugar.
Seems to be two parallel systems in the body: a sugar based system OR a fat based system (keto)
