I tested positive for EBV (EA, VCA and NA) and HHV-6, but CMV was NEG. I say positive on EBV, but my GP tends to discount the levels because they were IgG, instead of IgM and CFS doc at the time says that EBV IgG should never be as high as mine was and all 3 types were positive means reactivation. Do you mind if I ask what types anitbodies(?) you tested positive for (IgG or IgM)?
I took Valcyte for 3 months, but was stopped to try and get thyroid straightened out. I still have about 2 months worth and was thinking about finishing it up. It definitely helped me get through the day after I had been on it for a few weeks.
I understand about the sleep problem too as I actually had trouble with that before I got CFS, but became much worse after that. I was on Klonopin and Ambien, but am now going through a cycle of Xyrem. As tight as it is regulated they didn't have to put so much sodium in it, as it almost makes it not worth taking.
