Influenza
"I took Tamiflu within 7 hours of developing a fever.  I had full flu symptoms including headache, body aches, chills, fever even while on ibuprofen.  About two hours after taken first dose of tamiflu Fever broke and body aches subsided... I went from feeling like I would die to just a bit fatigued.  I had absolutely no issue with nasaeau- but I was having nausea due to fever before taking tamiflu.  Miracle drug!"
