Hi friends, I am 17 years old and work out a lot so I drink a lot of water (about 2 gallons a day). Some time I get a bit tired of it in the day. Is diet drinks bad in any way. Am I ruining my diet with them? I just started drinking diet. I really get bored of water or need to get full so I don't take too much drinking diet. Is there any other solution for me regarding this case?
