Due to a recent crash my Herpes viruses have grown out of control. My doctor has put me on Valtrex. It took me two weeks just to get use to the drug. Each time I took a tablet, I would feel sicker for hours. Then it would be time for the next dose and on it went. I am now in my 4th week and am tolerating the drug well. Unfortunately I have not noticed any improvement in my symptoms. So I wondered how many patients here on the board are on or have tried an antiviral and what were your results? If they helped you, about how long did it take before you noticed improvement?
