Sick and tired

Just in time for my brother-in-law's visit, I'm sick again. Sick, but sick and tired, too. This time it's a sore throat, runny nose, and backache. I'm pissed--I've been eating healthy foods, drinking lots of water, and getting as much rest as possible (last night I went to bed at 8pm). The germs just don't quit. Illness is the hands-down worst thing about my job.
