Summary
Prairie 72968 had long COVID for at least 2.5 years, with brain fog, POTS, exercise-worsened symptoms and low mood. Propranolol helped tachycardia and anxiety, guanfacine briefly cleared cognition but caused low blood pressure and muscle weakness, and LDN helped with tiredness. A fludrocortisone trial caused an extremely bad reaction, leaving them the worst they had been and doing pretty much nothing by March 2026.
