Hi. I'm messaging on behalf of a friend who's excessively tired and having trouble sleeping, waking up really early in the morning. I have insomnia and have for at least ten years, and I consider two hours sleep a night fantastic and I'll probably even that out by having a half hour nap the next day.
My friend sleeps the "average 8 hours", but every so often she goes through these stages of waking up at half five in the morning, after 6 to 7 hours of sleep, and she's very tired the whole day. (She's the kind that doesn't even wake up when they move around or wake up at accidental sounds. A heavy sleeper, I think.) After a few days of this, I'm constantly getting texts and calls about how she's feeling "so tired she feels sick" and how she feels about to fall asleep at any moment, feeling weak, shaky and about to faint, and I relate to how that feels, but I can't relate to the situation.
I get that bad when I've been awake for 4 to 6 days in a row, and that's not every time. It's completely impossible for me to imagine how or why someone would feel that tired when they're still managing in one night the same amount of sleep I would be about happy with in a week.
I know university is stressful at the moment, very stressful, and she struggles with an eating disorder which don't help, but I've been in those places too, so I still can't understand why she can't just get up and not be so exhausted.
I want to think this isn't about the sleep, it may be something else psychologically, which I could then understand. The ED she struggles with isn't bad enough at the moment to cause this.
Is there anyone that can tell me if this is actually normal for a person that normally sleeps a lot?
Thank you.
