I often feel mentally tired ,or slow, after eating. I feel normal before my first meal, and the longer I don't eat the more clear-headed I am, but once I eat and start digesting the food I slow down mentally, feel less able to focus, and kind of "dumb".
symptoms are bloating and having to go to the restroom on average 2x a day, with constipation or loose stools.
I have had a lot of tests, including those ruling out things like Celiac, Chron's, UC, and ALS.
If anyone has any experience or knowledge about this "brain fog", please post. Thanks
