Summary
Fjord 24122 had long COVID since 2023 with POTS, brain fog, insomnia and cholinergic urticaria. They credited fasting, a keto diet, rest, stimulant reduction and over-the-counter allergy medicine with the most help, and later nicotine patches and low-dose naltrexone for fatigue, energy and sleep. By November 2025 they were starting to get better after two to three years but still needed several medications to function.
