Summary
Starling 19697 caught COVID in January 2025 and a month and a half later had digestive symptoms, a raised heart rate and headaches. Famotidine 20 mg eased the cramps and was bringing their heart rate back toward normal, and two weeks of famotidine with Zyrtec ended the headaches. By May fatigue and heart rate problems had gone, leaving on-and-off cramps after dairy and sugar, managed with famotidine stints of up to two weeks.
