Both actually, I don't drink much soda period but Sprite is my beverage of choice when I do. If I want dark cola though I have to have Pepsi, can't stand Coke.
Coke products for me. My dd prefers Pepsi. I tell her she must be part Yankee. I used to prefer 7 up over sprite, and still do if it's in a can. But I'm highly addicted to cherry sprites from Sonic.
Im a diet coke addict!
However if Im somewhere, like party, where thre is no diet and Im forced to drink regular(yuk!), I do prefer Pepsi, but will drink either.
I actually put soft drinks down this past spring...it has been about 3 months now. I was up to about 6 24oz. Dr. Peppers a day, yeas I quit cold turkey, it was hard for the first 2 to 3 weeks but now I am doing great nothing but water and crystal lite here.
