I'm under 30. This recommendation came from doctor who specializes in herpes. She did warn me it might not work, but she has seen overall good results -outbreaks are less severe, rarer, or dissapear altogether.
I think it's been around five years.
There was a paper also on that, but couldn't find.
Why I'm sharing this information usually, because there are people out for who herpes is not annoyance but life disrupting virus. They often do not even know that there are antiviral drugs out there that work really well. They do think that there isn't much to do other than to suffer because when they were young or had bad doctor who said "oh everyone has it". My hope is maybe some people might go back to their doctor and say "please, it's disrupts my life" and they get appropriate treatment.
