Sorry, but I really need your expertise on pharmaceuticals at this point.
I can't go faster than 10% a month with the Valium taper without things becoming unbearable. At that rate, I will be off 4.5mg of Valium in another 24 months or so.
If you were me, would you stop the Valium taper and get the Hydrocortisone, currently at 15mg/day, at a lower dose... say, 5mg/day, before finishing up the Valium?
I don't think staying on that high of a dose of HC for another 2 years while I finish the benzo is a good idea.
