Summary
They link long COVID to two vaccine jabs after a Covid infection, with PEM, dizziness, gut problems, insomnia and vision issues, paying dearly for any exertion. In September 2025 a first Augmented NAC capsule improved sleep and energy overnight, though raising the dose worsened fatigue; a month in they had several good days a month but crashes still lasted days. SivoMixx and butyrate later fixed gut and sleep problems, and by February 2026 only occasional issues remained.
