Every since going primal, I've hated the taste of bottled water (and now drink less water than I use to)- we don't have a filter here, so maybe that's the problem. BUT! I drink anywhere from 4-8 cups of tea, and two cups of coffee a day. Only time I neeeeed water, is after I've been outside in the sun walking around.
Maybe it's time to invest in a filter. Or stalk someone that has filtered water, so I can try it first.
