Herbal/Caffeine-free Bulletproof Coffee / Tea for Adrenal Fatigue Sufferers

Coffee and possibly caffeine work by stimulating the adrenal glands, in essence using tomorrow's energy store (postnatal Jing in traditional Chinese medicine). Due to this and having adrenal fatigue, I have endeavored to make a caffeine and coffee-free version of bulletproof coffee? I've asked elsewhere but haven't gotten any decent answers. Below are the different variations that I have tried:

• Yerba Mate - tastes good and works well, but not indicated for the liver if you have liver probems (most people with adrenal issues have endocrine system/liver problems in my humble opinion) and it has caffeine - of course, as a biohacker, health effects trumps taste. The same can be said about Gotu Kola; it taxes the liver but it is an adaptogen, it is not a stimulant, and it does not have caffeine.
• Chaparral - a truly superior herb for the adrenal glands. Use with caution as it is a very powerful herb. It is also rich in Vitamin C.
• traditional chinese medicine herbs from my acupuncturist - gross and bitter but gives good effects.

Haven't tried but I have heard of:

• cannabis coffee

On a side note, what happened to the the full video version of Dave Asprey's Bulletproof podcast? Is it now iTunes or paid only? And why has he removed the ability to add comments to his videos on youtube?
