Out of curiousity, I decided to test my drinking water after reading your post (I bought my first roll of pH paper today). The water from my tap (cold) seemed to be around 7.0 as did my filtered faucet water. Not very accurate readings though because it's based on the color change. My distilled water was not nuetral and was at a 6.0.
I will be monitoring my own urine for the next week and decide whether or not distilled water is a good idea.
The first urine test I did today came out at 7.5 (or higher I'm not sure because it doesn't test higher than that) and I'm hoping that I'm not losing minerals from my body. If my urine continues to be very alkaline I will either try mineralizing my water with maybe sea salt or try to let the distilled water be energized by the sun to see if it changes the pH. I'll try my best to keep up with this and post my results if anyone's interested.
Thanks again Azurite!
If anyone knows how to get more accurate pH readings I would appreciate it :).
