9.30.23 || Jotting this down for the future: symptoms of a cold (congestion) started small on the night of Thursday 9.28.23 and appeared on Friday 9.29.23. As long as you remember to write down (1) the day that symptoms felt the worst, and (2) the day that symptoms disappeared completely, then in the future you can track how long it will take for your cold to last and subsequently make/change plans accordingly.
