I was on Valtrex for an entire year. It cut out the mild FM pain entirely in the first couple of months, but it didn't bring down my EBV blood counts. The FFC doc has taken me off Valtrex, and I started Famvir about two weeks ago. Starting this past Saturday afternoon, I have gotten more and more tired. I can barely keep my head up and eyes open now. My father-in-law died Sunday, and we are going out of town later today for tomorrow wake, Friday's funeral, and other family activies for the weekend. I'm not sure how I'm going to be able to keep up -- I just wish I could get back in bed and sleep 'til Monday. Unfortunately, not possible! There will be a lot of obligations. Thought I'd dash this off quickly to get a couple of hours of board time before we leave. Any and all suggestions appreciated!
