My husband is finally recovered from long haul. Took six months. I had a thread on it with lots of information but couldn't find it for you or I'd link it.

Lots of supplements. Brain fog was helped by Lion's mane. Finally got a script for low dose naltrexone that helped with the chronic fatigue.

I'm sorry I can't find the thread. This phone is not the best.

Here's the basics... turmeric, red clover tea, xtendovite, vitamin c, D3, k2, multi vitamin, e, selenium, magnesium, artemisinin, NAC, probiotics, glutathione, zinc, juicing at least 3 times per week.

He was really bad. Has RA, so I think that made it worse. Hopefully someone can link you to the thread. I'll try again later.
