I dropped sugary cokes a couple of years ago. I drank iced tea, very lightly sweetened, to transition, and now I drink caffeine-free diet when I want a coke, and I brew up iced tea by the gallon and sweeten it with Splenda. It does the trick for me.
Every once in a while I will have a regular soda, and it always tastes sludgy and gross to me. Although I will say, if I ever can get my hands on a soda made with real Cane Sugar, I always break. Those things are sooo much better than the HFCS crap.
Anyone else ever had Mezzo Mix. German Orange flavored coke, made with cane, it is the nectar of life. Thank god they don't sell it over here.
