I feel dumb after being glutened.

I now know I've been glutened when I suddenly can't remember anything (aside from the extreme bloating and stomach pain). After getting glutened during christmas, I went back to work the next day and I noticed I can't do math very well, I can't remember the products I'm being asked to get like I used to (people will ask for about 10 things and I could remember no problem). I'm forgetting important dates or what my work schedule is when I could remember it by heart. It feels like my brain is on low power mode.
