I had Covid last September and it was pretty rough for me . Still can’t hardly smell anything much and like you , the taste of almost any soft drink is terrible now . Any cola flavor is the worst and Pepsi used to be my favorite. They all have a strong chemical taste to me now .
Maybe Covid enhanced your taste buds to the point you can now taste all the chemicals used to make what the FDA calls our food.
