Over the world there are many names for carbonated soft drinks and from many base materials. Barley, Coco nut you name it. Here in our home it's diet Pepsi for she and ... well several choices for his self. Sprite to Mountain dew or a cola. I like coconut or fruit flavored soft drinks too. Even a Ginger Ale will meet my need. Water is to avoid unless taking a pill. There are varied amounts of fluid recommended/day. I drink my share of coffee too. I guess it all adds up and so long as you drink BEFORE you're thirsty I guess that will fill your bodies needs.
