I had covid late last year and had no loss of taste or smell at all. However, since then, sweet foods taste unbearably sickly. I have always had a really sweet tooth, but now chocolate, cake, ice cream etc are eating mouthfuls of syrup. Even weetabix or rich tea biscuits taste too sweet. I know people who have had the same after losing their sense of smell and taste but not people who didn't lose them.
