Zinc, D3, elderberry. Rinsed sinuses with Alkolol twice daily, oregano oil nasal spray, nettle and dandelion tea. It was much like the flu, to me. If I hadn't known it was supposedly Covid I would have thought "man, flu sucks this year". I am also morbidly obese with a rare neuromuscular autoimmune disease that makes me very very susceptible to sinus and breathing trouble and can lead to respiratory crisis o its own. My mother who has cancer and IBD got it same time and she had to sleep for a couple days straight so I stayed at her house with my 2 kids and spouse taking care of her and all them plus my disabled and failure to thrive sister who all had it. I got no sleep for two nights and we were all still over it before the week was up with no outside help or intervention.
