Eight glasses of water a day
I've always found it hard to drink the suggested eight glasses of water a day. That's a lot of water! (and a lot of trips to the bathroom).
Today I was reading in my Dr. Mercola newsletter that:
"There is little evidence for or against any of the supposed benefits of extra water, such as increased toxin excretion, improved skin tone, lessened hunger, and reduced headache frequency." -- from mercola.com
The source of the study is the Journal of the American Society of Nephrology.
