influenza
"Monday night, I started getting body aches and swollen, sore lymph nodes. Woke up at 3:30am with my 2 month old, and couldn't swallow without stabbing pain. By 8:00am Tuesday, I was on my way to the doctor with fever, chills, and the worst sore throat of my life (turns out one tonsil was enormous).  Started the Tamiflu by 3:00pm. So less than 24 hours from the abrupt onset of symptoms. Now we are at the end of Wednesday, and I can't believe how much better I feel! My energy is coming back, body aches are gone, and while my throat is still sore, I'm not crying when I swallow (yeah, it was that bad).  I am impressed. Do take with food though! 2nd pill was on empty stomach and I was throwing up for 15 minutes 2 hours later."
