I'm convinced my brother brought home some evil spirits from Panama or something. He came down with some sickness (maybe more than one) shortly after he got back and sure enough, he's passed on at least the cold portion of it to me and my uncle (visitting from Sydney, Nova Scotia). I went to bed last Monday feeling fine and woke up feeling miserable. Neo Citran, chicken noodle soup, juice, tea, halls, drugs, ... nothing seems to be able to get rid of it. Sleep might help but it's hard to get to sleep when you're hacking up a lung all night.
So as for those 4 days off from work, at least I got to relax a bit but it's tough to accomplish everything you want to do when you feel like crap.
