"Hell.They won't tell you about the risk of "rebound effect" until after you tell them you want to quit.Oh yeah, I'm constantly getting checked for HPV, even though I was vaccinated against it and have been testing negative (for HPV) for over 5 yrs. but thats the least of your worries compared to what else it does to your immune system. They want to have you on it until (if your lucky) you test positive for the JC virus,and take u off ASAP.Otherwise, you'll go unnoticed and risk a brain infection, but it gets worse, they've implied that even while testing negative for the JC virus you could still wind up with "pml? Pll?" ( I forget the acronym) but in short your actually risking your life or have "permanent disability"from this horrible drug"
