Work gatherings based around food are a huge problem, now and then, in several ways. For various reasons, I always got felt sick after eating at restaurants.
I'm curious because I have similar fatigue symptoms. But I had stopped eating wheat, so I had assumed it wasn't celiac. (Can't test without doing a gluten challenge)
But I completely agree that being self employed is the best way to handle this, and also that it is a major setback to productivity. My symptoms have improved in the past eight months or so and it's felt like an incredible blessing to simply have some normal days.
There is something called refractory celiac, which is permanent digestive damage. My mother had that and much of her small bowel had to be excised. I may have that issue. I’ve recently been to the hospital and have a few biopsies pending.
Now that I know I have celiac and can manage it by avoiding gluten, I just have chronic pain and inability to eat without not all of the autoimmune madness. This is a lot less uncomfortable but I am surprisingly almost as unable to work fully.
