Summary
The user developed brain fog and fatigue after COVID, needing naps every four hours. In July 2025 they began low-dose nicotine gum and felt like their old self while using it. They stopped after two weeks because of nausea, but the mental gains held, and by late October 2025 they almost felt like their old self again. They kept up cardio and weight training.
