Interesting comment in http://www.dilmahtea.com/web/faq.asp:

"... The human body requires a certain amount of caffeine and research
indicates that up to 10 - 12 cups of tea daily will not have any
detrimental effect on the body."

I'm curious as to how much caffeine people here require, and how much
they tolerate. I don't seem to require any, and can handle the
equivalent of about 10g dry leaf per day. That might make anywhere from
three strong mugs of EBT to a hundred gong-fu steeps.
