influenza
"Woke up in the am chest felt on fire. Went to work and fever started. Left work and went to doc and prescribed tamiflu. Took 1st pill 14 hours after initial symptoms. Fever broke by 1am and went to work the next day feeling slightly fatigued. After reading several reviews and keeping in mind what the doctor said, this medicine is most effective taken within the 1st 48hrs but clearly the sooner the better. It's a miracle drug if you act fast and don't drag it out."
