cold sores
"I LOVE this medication!!! I have suffered with cold sores since I was an infant, and it has always been something I just "dealt with"... AKA stay home from school, miss work, hide from the world for 2 weeks 2-4 times a year.. I was prescribed this medication in my late teens and it truly is a miracle drug! I take it as soon as I feel a tingle, or as soon as I see something pop up and it will either A: Get rid of it before it pops up, or B: limit it to the size it is currently and make it go away fast! 
I always keep some on hand!"
