disorientating

Wednesday I got up early & went to work only to find my roster changed & I didn't have to be there.
Thursday went in early to work...during the early hours, I agreed to return for nightshift. So I left early to come back later.
The plan was for sleep...I found the darkest room. But alas chose the hardest bed - a rather Goldilocks move I thought.
Just have to use what I have to get through the night. And try to remember which day it is...
