I was recently introduced to diet coke - when I tried it at 17 I hated it, I thought the aspirtin gave me zits. But after I quit smoking I knew I needed to cut down on my calories and since the average coke is over 300, I knew if I wanted to drink pop, diet was the way to go. Diet coke has less than 4 calories, water is the only drink less than that.
I drank diet coke like it was going out of style. During the summer in the hot months, it was the only thing that kept me going. And the nice little kick of caffeine wasnt too bad either.
Eventually I did have to ween myself off it, because two much caffeine is a bad thing. Also it has molassis and it gets a little gritty on my teeth. But I still love it and if you need a pick-me-up, diet coke is definately it!
