Herpes Simplex
"I woke up early in the morning and felt the tingle of a new cold sore. I went to the doc and got a prescription within the hour and took my first 400 mg pill of acyclovir. I used Abreva right when I felt it and a few times that night. I took 3 pills over the course of the first day. When I woke up the next morning the bump had not gotten bigger but had not gotten smaller either. It was hardly noticeable I should add. I took 3 more pills over the course of the second day and the bump has not grown any bigger. I woke up the 3rd morning and it has shrunk in size. I encourage everyone to get a large stock of acyclovir and take it IMMEDIATELY when the tingle is felt. Even if it is just maybe a cold sore. It is totally worth it."
