Acyclovir, then Valcyte (valganciclovir), dramatically reduced my symptoms. I went from rather severe (being unable to be propped up in bed) to relatively mild (being able to travel and walk fairly normally).
My husband Robert looked after me until struggled with prostrate cancer and was unable to care for as he was to ill himself then unfortunately he died so I have careers in to shower and make my breakfast and make my bed up which a great help.
