Three or four years ago I tried valcyte (I think, can't remember, brain fog is bad). I have recently crashed and my doctor wants to try famvir. I had to stop the valcyte after 6 or 8 weeks because I crashed, called in sick weekly and my boss made me sign some things to the effect that after a certain number of days it would be considered a leave (unpaid of course). I stopped so that I could work, as we only had my income. My health picked up though after I stopped and I was really functioning well, but now I have crashed. Anyway, is it effective, what dose should I start with, should I pulse (on and off), do I have to worry about my liver? Should I try LDN instead? I would really appreciate any guidance here. Please refer me to previous threads so that you are not repeating yourself. I tried a search but it didn't work (probably my brain fogged mistake). I take all kinds of supplements for methylation, detox, gut health, yadda yadda yadda so I know I need something else to boost me back to where I was.
