Summary
They developed long COVID after a third COVID vaccination, with palpitations, breathlessness, POTS-like dizziness, brain fog, muscle weakness, tingling and erectile dysfunction. Natto and serra caused about three weeks of Herx-like worsening, then they credited them with reaching about 95% by nine months, and noopept removed brain fog within 20-30 minutes. They later reported sexual recovery and said everything was fine, with mild acid reflux controlled by diet and PPIs.
