I am also looking at that India n herb, ordered some, well see. I also ordered some other herbs, Hawthorn and hawthorn berries, some other stuff that is not as heavy dose.
I will be going on Isocort, which is 'natural' cortisol, to start off with.
I cannot exercise either, but I try to fast walk for 10 minutes, which really wears me out, but exercise is needed.
Isocort, check it out, there is really nothing else I have found.
