Yes, I remember hearing about that woman in the news. That would certainly be "a lot" of water
The Government (and we all know how knowledgeable they are :-) suggests 6-8 glasses a day.
I know I use to never drink water but after the one trip to the hospital in my life for a digestive problem (that lasted 5 months and cost $30,000+) I turned over a new leaf and started working to make things healthier for me. I'm not into constipation if I can help it

and water really does help there.
I have Deerpark water delivered now and for awhile was despairing because I always ended up with leftover water when they were making the next delivery but I finally just cut back on how much they deliver and occasionally, like last month, just skip a delivery. So now I'm running out of water (but I cheat and use the bottled water instead of tap to make my coffee in the morning if I'm the one making it and pour it for the plants and animals instead of the chlorinated tap water.
