Hi Jon, it's nice to meet some other CM folks! Funny to do so on an espresso site
I don't find that the 'kidney* yin vacuity' pattern fits me. Actually my textbooks haven't been much help with this (they are meant more for the kind of patients you'd see in a hospital), which is why I'm trying to go with my own observations rather then theory.
On the first site I linked to above the author recommended taking bai shao (peony root) so soften liver qi, the idea being that coffee (similar to chai hu/bupleurum) dredges but doesn't smooth liver qi, which for some people could cause spleen vacuity symptoms, for example. I'd like to try this, but if I recall correctly bai shao doesn't taste good... bleagh! More ginger and licorice for me today
