cold sores
"I kissed a girl with cold sores when I was 17. I get cold sores on my lip whenever I am sick or very stressed. It happens more during the winter months. It took 18 months from my contamination until my 1st outbreak. I had outbreaks once per year for 3 years, then twice per year for 3 years. Now that I am 35 I get 4 outbreaks per year. I take 2 grams on Valtrax when I first feel tingly then 1 gram the next day (24 hours). This totally prevents my outbreaks! Valtrax works great!

Also, do not share food, drinks, or kiss anyone while you have a cold sore. It is very contagious! Keep your kids safe."
