herpes simplex, suppression
"I've had cold sores for as long as I can remember since childhood. I usually get at least 1 cold sore a year every year. I dabbled in taking lysine but usually it was once a Cold sore was forming... way to late. Last September 2015 I was under a period of stress and I got 3 of the buggers in quick succession. Since then I've taken 1000 mg daily of lysine and have now been cold sore free for 1 whole year! The first year cold sore free in forever! Thank God for lysine. Best prevention out there and cheap too."
