I get that loss of smell is a symptom of COVID-19, but what’s so special about 1 AM?
Anecdotal, but possibly related.
Loss of smell wasn't one of the more noticeable symptoms but it persisted for far longer and when smell suddenly 'turned on' and I could all of a sudden smell cinnamon when I sprinkled it onto morning oatmeal the smell seemed insanely noticeable due to its long absence.
