cold sores
"Valtrex is EXCELLENT. I, like most of you here, take it when I feel a slight tingle or little tiny cut on my lip. I just down about 4 of them and it's gone before it begins. I haven't had one cold sore in over 1 year now and I only got the virus about a year and a half ago. As you get older, the virus tends to be beat down by your body's natural immune system. "
