Where did you get that sugar dehydrates? I've never been dehydrated by sugars or anything like that.
Basic Chemistry and Biology.
Lol.
Sugar doesn't directly dehydrate you, but more so indirectly.
In most soda's the main dehydration is done by caffeine, but Sprite definitely will dehydrate you if consumed as your only drink
Edit;
Not that you should be worried about dehydration, as the alcohol you consume on a daily basis will already dehydrate you
