I have all manner of stomach/digestive issues on top of the brain fog stuff, although that is generally related. I have definitely spent thousands of dollars on supplements, tried probably hundreds of them. I want to get the TrioSmart breathe test to figure out specifically what my intestines are infected with, I want to get as comprehensive a food sensitivity testing panel done as possible. There are also lots of supplements that I know would help me that are not available where I am, for example bismuth (pepto bismol).

In your case, I would recommend getting some L Glutamine power and taking a bunch of that in the morning and at night. That would likely fix your brain fog or at least go a long way. Best resource I've found is brainhealthbook.com . What is your email? I'll reach out and we can discuss ideas, theories and strategies further.
