cold sores
"A long time sufferer of frequent cold sores. I'd get 7  / year that were the size of a quarter! I was prescribed Zovirax for 15 years. It didn't prevent the cold sore from forming, It just sped up the healing time from 10 days to 8. I tried Valacyclovir as a last resort and I can honestly tell you it is a miracle! Any time I feel a cold sore coming on, I take it and the cold sore doesn't even form! I have been cold sore free for almost 1 year!"
