My best friend has trouble with insomnia off & on. Lately it’s been kicking up again & she’s been on a rant about it. Totally understand, but today she was upset over sleep deprivation & that it was going to kill her. I’ve quite literally lived in the brain fog with CFS for just shy of twenty years now. I average about 4 hours of useful sleep every night. I feel for her, but at least hers will even out eventually. I’d love to have that hope.
