I've read articles that say the water in foods an drinks do count as water intake. However like most people have said I don't count that in my tracker. I stick to the pure water that I drink. . I usually get my intake in by drinking 8 oz when I wake up. 16 oz with each meal, and then misc sipping through the day. I try to cut off my drinking at 8-9 pm so that it doesnt have me up going to the bathroom at night.
Good luck on your journey, and drink up.
