I have had cold sores all my life and I get them severely, but for some strange reason they dissapeared when I had bubby #1. Now they only come back when I am pregnant. I was told by my chemist not to use zovitax whilst pregnant, the chemist's own brand of zovirax is safter to use becuase it doesn't have the key ingredient in it that they say can be harmful (I can't remember what it is called).

The L-Lysine tablets are great for prevention, and also help the coldsores heal quicker if you do have an outbreak. I am 6 weeks today and have woken up with my 1st one!!
