Influenza
"I have had case of severe flu a few times before but this time I went straight to the doctor to to try Tamiflu.  While the flu usually made me miserable and feverish for 4 days and weak for a few days more, I felt pretty good after about a 1 1/2 days and was ready for work on the 3rd day.  I will always go for the Tamiflu in the future.  In my case, when my face feels flushed, I have a lack of appetite, ache in my neck and back and a slight fever, it is time to act.  You need to start Tamilfu as soon as you see the first signs.  It is great!"
