This has correlation to lesser the outbreaks or make them stop altogether. I can attest to that.
This is what some specialist doctors recommend for patient with bad herpes outbreaks.
I guess this would be already good starting point.

How long has it been since you had the zoster vaccine?
Were you of an on-label age for the zoster vaccine at receipt or was it off-label usage? Put another way did you receive Varivax or Zostavax dosing and were you in the on-label group (1-50 for Varivax and 50+ for Zostavax)?
The data isn't great but there's a fair bit of anecdata as you report and in your link that suggests there might be some protection against HSV from the VZV vaccines, possibly based on genetics or age of recipients.
Also your link was broken for me but the below might work.

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.
