Me? Vitamin D3, zinc, Vitamin C every day. I have 5 days of Ivermectin waiting in the wings in case. Betadine Nasal spray if I been out in public when I come home, gargle with Listerine with alcohol. Keep the house ventilated. No mask for me if I am on the outside. I will wear it in a store I need to go in since the place is private property
