influenza
"Started feeling ill at lunchtime yesterday, by the time I went to the doctor at 7pm, had a 101° fever, chills, nausea, headache, muscle spasms, severe tachycardia, etc. Was prescribed Tamiflu, took first dose at 9pm along with Tylenol and Zofran. Took another dose this morning and already feel a night and day difference. Majority of symptoms are fine, still treating headache and low grade fever with Tylenol, but don't feel like I've been hit by an 18 Wheeler anymore. If you catch it early, Tamiflu works wonders. Take with some crackers because stomach can get a little bubbly."
