Why do I need so much sleep?

[BettyBakesCakes]

I need loads of sleep atm. Can easily sleep 11/12 hrs a night then the same the next night and every night. I had bloods done last year but they came back all clear. But it's not normal, is it? What's wrong with me?

I get this, too. I've been back and forth to the doctors asking for advice and hoping for answers but nothing because my bloods come back fine. Keep going back if something doesn't feel right. That's what I plan to do too, because there's no way it is normal for me to feel as fatigued as I do. I hope you get some answers, OP

I seem to need more sleep than other people I know, but I’ve always been this way. It’s frustrating!
I have a B12 deficiency, but it’s treated. No other physical causes

Could it be that your body is used to it so now needs it? That happens to me if I get into the habit of sleeping lots, but if i limit it for a while I get used to less again.
