Take vitamin-C (>2000 mg spread over at least 3 times during the day.  liposomal vitamin C will allow you to take more without digestive complaints).  Take Vitamin-D3 (30,000 - 50,000 IU if you haven't been taking any) and Vitamin-K2 (I generally take 1 vitamin-K2 for every 5,000 IU). Take Zinc (50 mg) with Quercetin (zinc ionophore to get the zinc in your cells which helps prevent replication of the virus) (EGCG works, too.)  Use a neti pot with saline with a few drops of povidone iodine and/or colloidal silver.
