Summary
Someone with long COVID described insomnia by April 2022. Magnesium before bed and thiamine helped sleep somewhat, and hard early-day exercise sometimes helped, sometimes backfired. By 2026 antihistamines (famotidine and Claritin) had resolved the insomnia, with magnesium and L-theanine also helping, and alpha lipoic acid may have helped with smell, while they also smelled potent spices daily.
