Valaciclovir - anti viral drug - for ME/CFS: what dosage have you found effective (if any)? Asking for a me. My GP has cautiously started me on 500mg daily. The one small scale trial was using 4g daily. drmyhill.co.uk/wiki/Valacyc...#MECFS#pwME#LongHauler

I did 500 mg daily. It helped get my cold sores under control when lysine wasn't effective anymore. Also helped me feel less fluish. I can only do it periodically as it messes with my stomach. I also need to avoid the ones that are blue. There are white ones available.
