> Anyone got any other experiences with things that cause brain fog?
Allergies and Food sensitivities.
These are often incredibly hard to diagnose because there are foods that we eat so commonly, we don't have a good control/variable separation for experimentation. In addition, allergies and food sensitivities don't develop all at once. They increase over time. This makes discovery even more difficult.
But it's almost always this.
As for myself, I had severe brain fog and fatigue. It turns out I was allergic to coffee. Looking back, I now see that it was something that became more and more severe over about 10 years.
It took me quitting coffee for several weeks for an unrelated reason to discover that it was the problem. When I started again, the stark difference in how I was felt made it much easier to diagnose. I got lucky really.
