Valtrex
"I have been getting cold sores since I was 9 years old, sadly when I was little they didn't know what cold sores were and how contagious they were. Therefore they were spread much more often than today. They are miserable, not only are they very painful, it's hard to eat as well but they are very very embarrassing. People look at you like you have the plaque. I used to suffer for 2 weeks during an outbreak but now I take valtrex at the first sign and if I catch it fast enough I don't even get the cold sore. If not then it's pretty much gone in 3 days. It doesn't get near as big or as painful and it's much easier to hide. I love this medication and can't say enough good things about it. try it you won't be disappointed."
