@herpesbaby I have been taking Valtrex (Valacyclovir) January through June, 6 grams a day as proposed by Dr Lerner. Most of my symptoms have markedly improved: Orthostatic intolerance, exertion intolerance, joint pain, fatigue, weakness, heat intolerance. I went from EIPS 1 to I would say EIPS 4.5 today, which sadly still means I can't work.
No symptom has disappeared completely, but almost all have improved, except headaches which I think are worse than they were.
That said, 5 months isn't nearly enough for full benefits to show. According to Dr Lerner, substantive recovery is expected to start after 6 months. Recommended minimum treatment duration is 1 year. Expected improvement
for those who respond to treatment is in most cases to EIPS 6-7 which means patients can work 40-hour office jobs, manage their households, have some social activities and perhaps do a tiny bit of sports (EIPS 10 is 100% healthy).
In June, I had to stop Valacyclovir because my kidney test results deteriorated. They fully recovered after 10 days. In the 3 weeks when I didn't take antivirals, my symptoms clearly got worse again, which indicates to me that - at this time, 5 months of treatment - results are not permanent.
In July, I switched to Brivudine, which is also a potent anti-herpes drug. It doesn't affect the kidneys but is more problematic for the liver if taken long term. I hope I'll be able to switch back to Valacyclovir in a few weeks.
Dr Lerner says, of thoseresponders who complete the full course of treatment about 50% have permanent improvement and can stop Valacyclovir altogether. 30% can reduce dose but still have to take it and 20% need to continue taking high dose Valacyclovir, which he says is usually well-tolerated even over several years.
Dr Lerner had CFS himself at age 58 and treated himself with Valtrex over 5 years. He recovered to a degree that he could run his practice, do research and attend scientific conferences, which I think is a pretty good result.
