I've been on Valtrex for about 3 months. I'm wondering if anyone else is having the same problems as me. At first if I miss one dose my symptoms came right back. So my doctor had me take it twice a day for a month. I'm back on once a day and now my symptoms come back about 4 hours before I'm due to take my dose. The medicine doesn't seem to work for 24 hours. Also, does anyone else have "continuous herpes"? I thought people got "outbreaks" mine never goes away!!!
