Ancient Greek philosophers usually did it often with vegetarianism.

> I am glad to have drunk water so long, for the same reason that
> I prefer the natural sky to an opium-eater's heaven. I would fain
> keep sober always; and there are infinite degrees of drunkenness.
> I believe that water is the only drink for a wise man; wine is
> not so noble a liquor; and think of dashing the hopes of a morning
> with a cup of warm coffee, or of an evening with a dish of tea!
> Ah, how low I fall when I am tempted by them!
>
> Henry David Thoreau, "Walden"
