I hear the nutritional suppliment Llysine does good things. if you feel one coming on, take one. The abbreva stuff really does work, expensive at $20 a tiny tube, but oh so worth it. My neice gets them all the time, and swears by L lysine stuff. I havent had one since I was a kid, so I have no clue myself, other than the whole derailed train of thoughts that now everyone at the big city hospital will be staring at my lip.
