I drink water mostly, by way of a Growonix R/O http://www.growonix.com/gx-series/GX300HF w/ high flow membranes. The water is quite pure and I test it regularly for PPM. Always 0 ppm. Nothing but H2o
Other than that, I juice using a Green Star – Twin Gear. I make veggie drinks using organic greens and carrots. I drink some Oolong teas [loose tea] too.
