I didn't sleep hardly at all last night. My joints are all aching, my head hurts, my back hurts, my sinuses have been bugging me, and my stomach is in a knot. I still have a bit of a fever, too.
If I didn't know better, I'd say I had the flu. I didn't go to work today because of it, and I'm hoping to be able to get some sleep here-and-there.
I would say you have the flu.
