Summary
They caught COVID at Thanksgiving 2021 and spent about two years with fatigue, brain fog, memory problems, tingling hands and feet, tachycardia, acid reflux and anxiety. They credit NAC, started in 2024, though unsure if it was NAC or time, with turning daily struggle into occasional flares, and Zyrtec with easing their racing heart. A COVID reinfection in early 2023 also made their symptoms vanish overnight. They are back to running and yard work, with occasional flares.
