I've been doing antiviral therapy for about 5 months now (Valtrex) and taking the transfer factor 6000. All of this is through FFC. The doc wants me to go down on my antiviral meds and I'm really scared to do this. My sore throat came back again...how can I get this to go away? It's constant now...so now I think one of the viruses are back. When I go off the transfer factor (if i miss a few days), my stomach starts hurting again from the HHV6. I don't think I"m going to go off of them just yet...does anyone have any advice??
