I made my own water kefir last year for about 9 months at it worked great! I only stopped because I eventually got too lazy to make it (depending on the weather, every 2-3 days). Whenever I could feel digestion issues coming on, I'd drink a half a liter and be good to go. Maybe it was just the placebo effect, but whatever works, right?
I got started on the whole thing through a friend who was living in Rwanda at the time and looking for natural ways for her family to stay healthy in spite of the many water and food bugs they were constantly coming in contact with. I have yet to read it, but she recommended the book "Wild Fermentation: The Flavor, Nutrition and Craft of Live-Culture Foods" by Sandor Katz. It's on my list of to-dos for 2013.
