cold sores
"I rarely get a cold sore (normally once every two or three years), but when I do they are mostly quite large and last for at least a week. So when one popped up in the morning and had already started to blister I went to the chemist straight away. He suggested I try this (1500mg one dose). Wow did it work, cut the time in half and scabbed alot quicker. I continued using cream as well. Only downside was on the day of medication I felt quite drowsy and had a mild nagging headache until the next morning. But so worth it. I will be taking this everytime from now on!"
