herpes simplex
"I’ve been having cold sores since I was 12 on my lips and face. I tried everything and nothing would work. My doctor prescribed me this when he realized how serious it was. I was getting them sometimes one right after the other one! 
I’m supposed to take one gram a day, but I found that when I did that I still got them frequently. So I only take it when I feel a tingle , I take about 4 and it never comes out.
What sucks is when I don’t get the tingle and I just wake up with a full blow on sore/sores. Overall medicine really helps though!
Completely free with my insurance as well!"
