cold sores
"I got my first cold sore when I was 3 years old.  I am now 36, and have tried every topical ointment available over that time frame, both prescription and OTC.  If you have recurrent cold sores you know all too well the stress associated with having one.  A few years ago my doctors MA suggested I take a sample of Valtex, keep it on hand, and when I first sense a cold sore coming, take 1 gram, then wait 12 hours and take another gram, and do this for 2 full days - or 4 total doses.  I was nearly sore free in 2 days.  It works best if you catch it early, but still can be effective on a developed sore.  I now ask my doctor for a 30 pill supply and keep it at the ready.  I find I fill it once a year."
