I am curious if anyone has tested XMRV + after taking Valcyte (or Vistide)? I have been on Valcyte for 2 years (Dr Lerner) and have gained most of my improvement in the last two months. I want to get tested for XMRV, but am waiting for the new serology test (and some money) but am concerned since I have shown improvement on Valcyte that maybe it will affect XMRV test results. For anyone wondering: I am still physically limited and tire easily, but I am no longer CONSTANTLY fatigued (thank God!). I can take little walks (10 minutes) but still need a lot of rest. This is improvement for me since I was constantly on the couch laying down with fatigue and headaches.
