Herpes Simplex
"I suffer from cold sores once a year usually October or  November but I find Abreva works well when first signs of cold sore appear. I can&#039;t ever seem to catch it at the &quot;first tingle&quot; usually wake up with one trying to pop out. I immediately throw on some Abreva then take some lysine pills and some Vitamin c. Seems to heal it fast . In like 3 days. If the blister sadly appears I use Abreva every other hour and take 2 lysine pills every other 4 hours. "
