Can I keep genital herpes outbreaks at bay without taking preventative antibiotics daily? First contracted gen herpes couple of years back and quickly realised that much like a coldsore, an outbreak can be once a year or so. However, chemo cancer treatment for much of 2014 meant the need for preventative antibiotics (famciclovir). Cancer all clear now (NHL - check up CT and bloods Feb 2015). SO - I am VERY keen to minimise any and all pharmaceuticals and any dietary advice re keeping gen herpes at bay would be MUCH appreciated. Many thanks x
