I have been mostly bedridden and totally housebound for a few months now. Before getting sick I was a perfectly normal functioning human being. The last few months have been torture. I have an active infection of HHV6 and also I have some high titres for EBV so that may be a contributing factor. Anyway, today I begin Valcyte. I hope so much this helps! I'm not sure if I want to start with the full 1800mg per day or start with 900mg and see how it goes. Probably tonight 900mg. I'll keep you updated!
