Around the beginning of September 2020 I started drinking 100 oz of plain water every day. Seltzer, Diet Coke, beer and coffee did not count. I still drink some of all of these, but for the 100 ounces goal it had to be tap filtered water. Why? I’ve read articles over the years touting the many health benefits of high water intake. People said it made their skin clearer, bad breath went away, fewer muscle aches.
