Lysine
"After over a decade of dealing with outbreaks, I finally decided to try Lysine last week.  My outbreaks are triggered from sex - nothing else.  If I go for long periods without sex I don't get any outbreaks.  Once I have sex or ejaculate I start to feel the tingle a few hours later.  Sometimes I can have sex two days in a row before I feel the sensation.  I bought the Lysine after getting the tingle and getting that "nervy" feeling under my skin.  I took 1000mg every three hours on that first day.  By the next day, the feeling was almost gone and  I took three more 1000mg.  No outbreak.  I was so happy.  I had sex five days straight and still no tingle.  I haven't taken any for the past two days.  I will continue to experiment with it."
