What's up!
Yup. I thought the same thing. I drive AndroGel (Expensive) for over 6 weeks, as well as Cortef and Amrmour for 2 months. I was up to 30mgs of Cortef and 3 grains of Amrmour. I felt NOTHING with either of the three meds. I also tired provigil, accupuncture, TONS of natural remedies...bla bla bla... I've tired a lot and nothing works. I'm really hoping the anti-virals I'm on work.
I think you need to be tested for EBV/CMV, as well as HHV6.
It sounds like you have a good doc willing to try different things.
What you need to do, is be your own doctor. Think to yourself : "When did this start"? Where was I? Was I doing something? Was I sick at the time?
There are a LOT of factors that lead to CFS. Be your own doctor and be proactive in finding your way back to health.
