cold sores
"I used to get cold sores frequently and have become so anxious about getting them that I keep a script for Valtrex in my wallet. After three years being cold sore free, I felt the burn and saw a patch of redness on my top lip. I immediately went to the pharmacy, filled the script and took my first gram of Valtrex within an hour of the first tingling/burning. I went to bed and woke up perfectly fine [and took the second dosage nonetheless]. I have no cold sore, no redness, nothing. I can't begin to tell you how much of a relief it was to wake up without that horrible throbbing swollen blister. I so highly recommend this. I can't imagine being without it now."
