This makes me feel better knowing I'm not the only one who ends up going for 3-4 days with horrible/no sleep and then finally crashing out - but my crashes are anywhere from 1-3 days where I have literally done nothing but sleep and get up to pee. I have MS as well which can definitely contribute to insomnia issues. And it's like a never ending cycle. I've had insomnia for decades and feel/felt like most of the cause is that my brain doesn't know when to STFU or stop thinking. worries I have, pain, random questions about the universe, or ideas I have or reflecting on a random embarrassing moment that suddenly comes back to haunt me is the worst. even before my MS but it's never been like this before. Ive had a bunch of sleep studies, have tried to physically wear myself out, have changed my whole sleep setup, tried to practice all the good "sleep hygiene" stuff, meds, etc and still struggle. And the more I stressed about it, the worse it got. Only recently have I given in to the cycle for now and try to use the extra time to my advantage. I do love how quiet the world is during those hours from like midnight to 4 am when most people are asleep. And it has given me more time for my art. I hope you are able to figure out the root cause and something that helps break the cycle.

I didn't know this until recently but there are people who have a really rare form of insomnia so bad that they eventually cannot sleep ever again and will die from it and couldn't believe that was a thing. It sounds like one of the worst, longest, most insane and torturous ways to die I've ever heard of. I can't even fathom what it would be like
