cold sores
"I have suffered from embarrissing cold sores for years.  My doctor told me about a single day dose of Famvir (1500mg).  He wrote me a script so that I have them on hand when I feel an outbreak coming.  I soon as I feel the outbreak, I initiate the therapy and the cold sore does nothing more than get a little red for a day or so.  No more full blow outbreaks, this has been wonderful."
