Larry: Do you only take Acyclovior when you have symptoms? Like say if you get a cold sore, or if you have an vertigo attack? I'm going to stop, but I don't know if I should go 2 weeks on and 2 weeks off, or go monthly, or just when I'm starting an attack? But it's helped me, and I don't want another attack, I'm almost deaf in the right ear, and the other has tinnitus as well, but I haven't lost as much hearing in the left ear. I know if I have another attack my hearing will be damaged even more. I thought the whole thing with the Acyclovior was to control the virus from recurring, and without the daily use of the drug how can that be maintained?
