Cold Sores
"This stuff makes a huge difference in the duration and pain of cold sores.  My dentist prescribes it for me because without it, I get a cold sore every darn time I go to the dentist.  For those who have problems with frequent outbreaks, do some research on things you shouldn&#039;t eat.  Nuts and seeds are huge cold sore triggers because of the arginine in them.  Other things that will trigger and outbreak for me:  too much direct sun on my face and too much exposure to extreme cold on my face.  If I&#039;m really careful about avoiding the things that cause me problems, I can prevent them but it&#039;s nice to have the valacyclovir for those times when I don&#039;t get it right."
