I drink maybe a liter a day. If it’s hot more but I’ve noticed since I went no carb I do not need much water.
I have an 8 oz latte in the morning an hour after I wake up and a 6 ounce americano midday. But I’m not thirsty at all until maybe 1 or 2 o’clock and drink maybe one glass of water.
After dinner I get noticeably thirsty and drink maybe 24 ounces of water. I don’t count but it’s usually a liter or so total.
