To those consuming this, 100% try it. The first 3 or 4 days suck because your body expects calories with it's drink and the buzz of sugar and caffeine. You can escape this by having a small chocolate with your water when you feel the craving.

Second point, mineral content, processing, temperature, and plumbing play a big role in your enjoyment. Personally I can't drink cold water, it has to be room temperature and tap water here is too mineral heavy. Instead I refill 5 gallon water jugs and use a water crock.
