I dont drink it very much...only when Im at work and its one glass but I found that when I drink even 1 I want MORE water cause Im more thirsty...Lately Im drinking around 80 oz of water a day....(which made me gain water weight which Im very unhappy about)....Diet drinks are horrible for you cause of something that they put in it is also in rat poison....I heard that and it scarded me off it for life!!!
