Sorry to hear both of you had and are dealing with Covid. My Mother is just now recovering from it and even though some of the symptoms disappeared she is somewhat still dealing with it. I couldn't imagine having no taste or a massive headache or even coughing non-stop like my Mother had for over 2 Weeks. She was really pale in the face during those two Weeks mainly due to her not wanting to eat with the lack of taste so I would say even with no taste you gotta eat and drink plenty of liquids.
