The worst that I have felt in a long time. I just had a nap - I've woken up from it more tired than I was when I went down for it, with a sore throat, dizzy, and just generally in bad shape. U.G.H.
Oh man, I hope that martian death flu hasn't hit you on top of everything else. My sister is just getting over it. (((hugs))) Get some more rest and drink a LOT of water.
