You could try IV cidofovir, or would you have trouble convincing a doctor to prescribe it? I believe Dr. Peterson has used it.
You could also consider artesunate or tenofovir.
Valganciclovir (Valcyte) inhibits EBV:

The side effects of brincidofovir are scary enough that I wouldn't want to try it without a trustworthy doctor prescribing it for me. Black box warning for risk of sudden death with prolonged use.
On another note, there might be a way to monitor if an antiviral is "working" by monitoring your monocyte count. I got fairly significant monocyte drop after taking only 500mg/day of valtrex for a few months, unfortunately stopped because even at the lower dose it still made my SFN worse. That was my 3rd try with this drug. I'm almost ready to give up and try cyclophosphamide.
