Tested positive December 15. I was sick as a dog for about 10 days. Then I felt good. But I kept testing positive 3 more times. It took till January 12th to get a negative result. Now I feel great. BUT I still have no sense of smell and about half of my taste buds. I can stick my nose in a jar of Vicks Vapor rub and nothing. So who has some lingering side effects?
