I'm against it depending on the ingredients. Most of the mainstream stuff, NO WAY. There is so much crap in there!!! I won't even drink it myself unless I'm absolutely desperate for something to drink and that's the only thing available.
Natural stuff that is caffeine free, no problem. Not that I stock that in the house anyway. I prefer fruit juices & water over pop any day.
I know I'm rather the odd one out here and sure maybe it won't kill us but it's not good for us either so I don't see the point in consuming it.
DH still drinks it though. At least I've got him on some healthier stuff.
