Summary
Dove 45419 caught COVID in June 2024 and developed long COVID with brain fog, raised heart rate, headaches and light and sound sensitivity. Mild at first, by March 2025 it was bad enough to stop work. A low-histamine, plant-based, low-glycaemic diet and rest helped most, along with DAO and antihistamines; brain fog and food reactions improved. A December 2024 reinfection, famotidine-linked SIBO and a chronic headache starting around late December 2025 complicated things.
