Summary
Cedar 71019 described long COVID with new social anxiety, brain fog and crashes after workouts that raised their heart rate, feeling brain dead in the first year or so. They credited vitamin deficiency correction, methylation support, NAC, detoxing and not pushing physically with helping. They crash less now but still avoid raising their heart rate and still deal with issues. A third COVID infection after a week of finasteride left them messed up.
