See if you doctor will let you try Low Dose Naltrexone (LDN). I am 5 long years into Long COVID and, though things have improved, I was spending most of the day pacing my use of the minimal energy I had and lying down due to extreme fatigue. I started LDN in February and slowly titrated up to 4 mg per day. It has flushed most of the inflammation out of my body so my pain has gone from a 6-7 a day to a 2-3 out of 10. My skin started clearing up about three months into treatment and my energy got a boost about month two. Now after 8 months of treatment, I only have to lie down about 3 hours a day...and, though I still have to pace myself, I can walk 1/2 a mile a day, go out to coffee or lunch with friends...and wash my hair without using up all of my energy for the day.

Initially, the 1.5 mg dose made me super sleepy so I took it at night. After about two week, it gave me insomnia so I now take the LDN in the morning. It did give me quite trippy dreams that were quite vivid but not scarry. No other side effects for me.
