My latest theory is that we feel the fatigue when our immune system is working. Just as when we get a flu virus (by we, I mean humans), and the flu is doing its destruction for three days. But the sick feeling is from the immune response.
So, I think there is an ongoing see saw battle going on against XMRV in us, also against the reactivated viruses. So the virus is being destructive on our good days. We do too much and the cortisol, hormones or whatever turns on that virus. Then, our immune system kicks in to fight it. And that's when feel fatigue. But, for many of us, our immune system starts to win the battle, and so we feel better. And then we do stuff. And the virus starts replicating from all that cortisol or hormones. And we don't know it. And it is an endless cycle.
This is why we have push and crash. Unlike HIV that wins the battle and kills the host. We are in a constant Vietnam type battle in our bodies.
Call this Tina's #2 hypothesis.

XMRV certainly could explain many things, including stress intolerance and Post Exertional Malaise
