First, 20 cups would I believe be a lethal dose! So hope you are
exaggerating.
I have a friend who wanted to stop coffee but couldn't (headaches), so I invited her to test out something I'd read,
that Angustura in potency will remove the craving. She used 12c and
took only a few doses, said it worked great, and quickly and lastingly.
(She went back to coffee some months later during a time of "stress",
but drinking less than before, and hasn't wanted to "bother" quitting
again.)
