Hi Everyone, I was wondering if anyone's done research on the efficacy of lower doses of antivirals versus higher doses for CFS? Are there any studies out there? I have one doctor recommending a lower dose of Famvir - 500mg, while another doctor is recommending 2000-3000mg Valtrex and I'm having trouble deciding on which approach to take. I'm always hesitant to take more than is necessary due to potential toxicity issues, but I don't want to take away from the effectiveness of the treatment plan. Thank you.
