I dunno, I switched to Coke Zero years ago and normal "full fat coke" now tastes sickly syrupy. I don't think it's strictly speaking the taste so much as the texture but it's very difficult to drink normal coke now.

(Of course, Coke Zero seems to no longer be a thing at least in Australia, we now have No Sugar Coke which is different and IMO not quite as nice but that's what we get.)
