So tired it's ridiculous

[OwlRightThen]

I'm so tired it's silly. I slept from 11pm-until 9.45 today, did a couple of hrs work and fb/mumsnet scrolled then napped from 3.45-5 (only woke up as the phone went). I have blood tests tomorrow but apart from the tiredness I have no other symptoms. Any ideas?

Have u asked specifically for feretin checked?
I was very tired - had feretin checked - was under 10 - had feretin iv in hospital

Also had a colonoscopy - there was a bleed in me that may of been caused by polyps that got removed
