Turns out it was from Mono-Sodium-Glutamat (Natrium Glutamat) !!!

Here's my story, followed by some info I've accumulated on MSG:

Below "my story", I'll paste a response I got from Outback Steak House in response to my Mono-Sodium-Glutamat (Natrium Glutamat) inquiry. As you can see, it's not simply in soy sauce at Chinese food restaurants.

Subject: My Mono-Sodium-Glutamat (Natrium Glutamat) story . . .

For years, I've been using powdered egg protein shakes (with 4,500 mg of glutamic acid per shake).

I was adding 15,000 mg of L-Glutamine powder to the shake to help keep my intestines healthy.

I took lots of fish oil gelcaps, and lots of other gelcap form factor supplements.

Although I would not buy prepared foods for home with MSG, it was never on my radar when eating out. (KFC chicken is so darn tasty!!)

Prior to 291 days ago, I was a healthy happy 41 year old male, going to the gym 4-5 days/week,

291 days ago my problems started with a terrible itchy skin rash, which escalated into terrible brain fog and mental confusion. I thought I was developing early Alzheimers ( e.g. leaving stove on, drove through an intersection when I got confused as to which traffic light changed).

It then progressed to muscle coordination and clumsiness problems (e.g. dropped a bottle of vitamins at the Vitamin Shoppe - I never do that).

Eventually I developed stiff jaw (hard to chew) and incapacitating muscle paralysis; I pulled a muscle in my back and literally could not get out of bed - I felt like a roach which had been sprayed with a can of RAID)

Much to my relief, when I went on an Elimination Diet of only chicken, rice & salt for several weeks, all symptoms resolved.

Though food challenge after food challenge, and keeping a rigorous food diary with 180 columns in Excel, I eventually figured it it was free glutamic acid. The light bulb for me was noticing that it seemed when I had my protein shakes with L-Glutamine, I seemed to do worse. Since glutamine sounds like glutamate, I started researching that and then the previous 291 days just "clicked". Indeed, when I was consuming the most MSG, indeed my symptoms were at their worst.

For example, I purchased a slow-cooker and cooked everything from scratch, for a really long time 10-12 hours. At the all-time worst point, I started slow-cooking corned beef brisket, eating 10 oz / day for 8 days (then that paralysis episode occured). I had no idea at the time I had my own MSG factory right in my slow-cooker: cooking protein for long periods of time breaks down the protein, liberating the free glutamic acid. Of course, slow cooking corned beef which was already heavily seasoned with MSG was a disaster!

A few months later, trying to be healthy, I started making home made chicken bone broth gelatin (slow-cooked chicken carcass for 18 hours). Again: I was making my own MSG at home and had no idea!

The sweet potato is rubbed with soy bean oil and baked. Then it is topped with brown sugar, honey butter blend (butter blend is palm kernel oil, soy oil and butter) and pure honey and then a sprinkle of cinnamon.
