What /u/IamSauerKraut said is true. Doxy can mix up the gut... In my Lyme case I ate a lot of Sauer Kraut, Kimchi, and other fermented things along with a diversity of fresh fruits and veggies. It too me close to 6-months post-Doxy to regain my functional memory back and I'm not convinced I ever got north of 85% of what I started with. I've had to come to embrace the new normal and change how I do things.
