Buhner antiviral protocol side effects? Please help!

I had a herpesvirus reactivation, so I'm doing something like Buhner's CMV protocol adapted for neuro symptoms, which is:

1. Systemic antiviral: Berberine
2. Stimulation of lymph & spleen: Red root
3. Reduction of cytokine cascade: Chinese skullcap, licorice, and cordyceps
4. Protection of neural cells: Chinese skullcap, cordyceps
5. Inhibition of viral infection of neural cells: cordyceps, licorice, Chinese skullcap
6. Regeneration of damaged neural structures: Lions mane

For a few days, I was doing much better. Then on day 5 I got achy and tired, lymph nodes swelled up, and I was puking my guts out and couldn't keep down any food or drink. I'm on day 3 of intense nausea but can keep some food and medication down. I was feeling better, took some of the antiviral protocol again (I think I took one capsule of each) and now I'm achy and tired again. During the ~36 hours of not taking any meds, my small fiber neuropathy symptoms got worse.

Do I power through? Do I stop?

I'm also taking Valtrex and Celebrex, prescribed by my dr, but my dr does not know about the herbals.

Any insights for what these side effects mean? Someone suggested to me it may be analogous to a "herx reaction" that people with Lyme get when they do these protocols, which would mean I should keep going. But I don't know anything about herbalism. I just jumped into this out of desperation.

My products come from Bulk Supplements and iHerb.

Would appreciate any and all insight. Thanks!
