I was never an "eight glasses a day no matter what" person
but I often drank water if I felt tired, thirsty or hungry and it adds
up over the day. I may have figured out why I've been
drinking less the past several months.
First, I'm consuming very little in the way of prepared foods including canned soups, frozen dinners or restaurant fare. These all have a lot of salt. Second, when so much of my diet comes from fresh produce I get a lot of fluids naturally from the food. Does that sound like a reasonable explanation to you?
