This CMV will not go away

My CMV level has been low positive for the past three weeks. That might explain some the diarrhea issues that I have been having. They are going to put me back on the Ganciclovir for at least two weeks. The good thing is that I can do it myself at home. The bad thing is the cost - my insurance only pays 80 percent and the drug is expensive and the drug is rough on my blood counts (as will be the Gemzar).
