cold sores
"I get cold sores maybe once or twice a year. I keep valtrex on hand and if I take it quick enough when I have the feeling one is coming on, it won't even appear, if I wake up and I have the tingly feeling on my lip and I take it, it will reduce it significantly.when  you feel the tingling make sure you take the full dose not just one. Also the cold sore healing patches by polysporin are amazing! If you get a full out cold sore and put these on It will shrink it almost down to nothing."
