Summary
A man got mild brain fog and a raised heart rate from the J&J vaccine in 2021; Covid about seven months later made it much worse. He credits time, rest, pacing and cutting sugar/carbs, and says exercise still brings days of PEM and brain fog. At around 1.75 years he estimated he was about 50% recovered and still significantly limited, though he could walk and his heart was improving.
