I.CAN.NOT.STAND.COKE! Diet coke is even worse. Sprite's OK, but I'd prefer 7-Up over it. However, my go-to is diet pepsi.
I was one of those that actually liked "New Coke" when it came out ... was it '85 or '86? Up to that point, it was pretty much all coke - or even RC. When that was dropped when they went back to "classic", I switched to pepsi.
