Rhonda: more than a year ago

At the advice from his doctor, my husband takes L-Lysine at the very first signs of a cold sore and then continues to take it a couple times a day for a few days. My husband swears it makes a huge difference, which says a lot as he isn't usually the type to take medications or supplements (he'll even suffer through a headache rather than take a couple of Tylenol).
