In their words
- Condition: Long COVID
then went back to my normal long hauler baseline
In context ↗ - At worst: Mild
they put me on lighter duties because I was unable to think straight or hold anything in memory for quite some time
In context ↗ - Now: Relapsed
I rebounded pretty hard and unfortunately when I went back on it it didn’t have the same effect.
In context ↗ - Began after: COVID
no hospitalization, no drop in o2, no issues with breathing or heart ... would be considered a very mild case of covid

Summary
A software engineer who developed cognitive long COVID after a mild infection in January 2020, with memory loss, word-finding trouble, tinnitus, insomnia and anxiety. Aspirin, statins, dexamethasone and hyperbaric oxygen helped for a time, but the gains wore off and later COVID and flu infections left them worse. Five years on they still had cognitive problems, poor sleep and tinnitus and relied on fasting, red light therapy and aspirin.
