At 4:30 this morning I was crying for my pillow!

I am not too sure if working night is actually a good thing for me!! At around 4:30 this morning I would have actually severed a limb in order to feel the comfort of my pillow. I got home this morning and I had a massive headache, such that one of my ears was ringing. Is that normal?? Hope not! I am just up for a bit and I still have a hint of a headache. Oh well 1 down 3 to go and then it's three days off for me!
