If I take Lysine L-Formula 500 mg, I don't seem to get as many cold sores. Also try Herpecin-L (a cream over the counter). If I put this on as soon as I feel one coming, it doesn't get near as bad. BUT I have to put it on 4 or 5 times a day untill gone. Campho Phenique make my cold sores even worse.
