I'm offering what worked for me. There's other stuff out there that might work, but I haven't tried. For example, I've heard folks talk about paxlovid working to alleviate symptoms, or using standard courses of antivirals, and so on. I'm here sharing my own experience.
If I've dismissed anyone, I sincerely apologize. That was not my intent.
When I say "it sucks, but you can make it through" my desire is to offer hope to a group of people - that I'm a part of - that often lacks hope given the severity of their symptoms.
As for efficacy, I'd invite you to look into mitochondrial dysfunction and how long covid is related. I'll note that a carb heavy diet is one of the ways to reboot energy production on the body, which can be potent for reducing fatigue.
