I really never drank much water till I started low card diet a little over a year ago. I knew water had to be a part of it and started buying bottled water from Sam's, 28 24 oz bottles for about $6, about 20 cents a bottle. It tastes fine, but out Chicago tap water tastes great too, I just do the bottles for convenience and keeps me on track drinking throughout the day. I drink about 3 a day, so that is like 9 8 oz glasses, more than I used to drink in a week. Our family mostly drinks tap.
