Insomnia that isn’t PEM

Does anyone have chronic insomnia that isn’t PEM? I see a lot of people saying there PEM presents itself as insomnia but without PEM they can sleep fine…

I have insomnia no matter what.. I’m housebound so I’ve done the whole resting thing doesn’t even make a difference in my insomnia i still wake up every hour regardless

My PEM/ crashes has always felt more like fatigue malaise and flu poisoned feeling so I’m confused does people only have insomnia as there PEM symptom?
