Sorry, but this argument doesn't "hold water".  (Yikes, a thousand
lashes with a wet noodle for that one!)  Diuretics haven't been shown to
increase the need for water-soluble vitamins, and mild diuretics such
as the caffeine or theobromine in tea and coffee certainly would not
be expected to contribute to this.  This is probably because the
excretion of ions by the kidney into the urine is an active process
which doesn't contribute greatly to the excretion of vitamins unless
there is a surfeit (as would occur in high dosagepr.)  You might as
well argue that it's a bad idea to drink lots of water.
