Kakie, Please, don't get more worries. Stop your stress for a while. This isn't helping you at all. Valtrex is better than Acyclovir and they DON'T have any negative effect on friendly flora and they don't aggravate your candida either. You probably have HV-1 or HV-2 and there isn't any link between them and a chronic candidiasis. Of curse, anything that load your immune system isn't good for you. Please, don't panic with everything you read or find.
