Any idea how long the bad stretch lasts, for most people?
Now I'm really in the hearsay dept, but it seems like people have mentioned that it lasts about a month, with a lot of variation from person to person. For me, it didn't start until 4 months after I started Valcyte and it lasted 8-10 weeks, although it wasn't the same "bad" the whole time. I don't think it's common to have it that late or that long.
