Glad everyone is getting through this, I have not had it that I know of but know a lot of people who have, one of which was pretty serious but never admitted, he still has lingering effects.
I have been taking Lomatium root(biscuit root) The Washoe used it during the 1918 flu epidemic and amazingly none of them were effected while people were dying all around them.
My wife is an Ayurveda practitioner(ancient India natural medicine) and knew about the root. You can get pills or tincture , the tincture is gross, tastes like really bitter weeds!
I have no idea if this is helpful, am not a doctor so do your own research, but it is simply oil from the root of the plant, some people get a rash from it. Pretty amazing when you research the Washoe and the flu epidemic!
