Summary

Takes cetirizine nightly (dose not specified) since 2021, along with probiotics, for long-COVID symptoms.

The page does not state how severe or how long their illness was before starting, but continued use since 2021 implies the benefit has been sustained, though this isn't explicitly confirmed as lasting without fading.
