Ann...I also struggle with fatigue. Not daily but it comes and atkes me out for a couple of days. I also struggle with insomnia. The long COVID DR. prescribed 300mg. capsule of Gabapentin, one capsule a night and a compunded capsule of 1.5mg of Naltrexone. It's compounded because it's not yet approved ny the FDA. I took both for the first time last night and slept the best i have in several years. Now, I felt groggy this am and needed more sleep. Because it's Sundy, i did sleep in. I will take the same dosage tonight and if i continue to feel sleepy in the am hours, i will consult with the DR., over dosage. But it sure beats the sleepless nights.
