I grew up a Coca-Cola fiend, and I had it bad too. My mother moved us around a lot, depending on the guy she was dating at the time. And one guy we lived with for 4 (a record for us) years when I was 10-14 put me on a 1 Coke-a-day regime. He'd buy an 8 pack of the old tall recyclable bottles in a carton and they'd better last all week.
But when I was an exercise freak in the 90's, I went diet-everything. Diet Coke was a staple, but no more than one a day since even diet soda isn't good for you. Then when Coke Zero came out ... I was in heaven
When I moved to Texas, everyone was all about DR. Pepper, I guess since it was invented here. So now I'll bounce back and forth between the two, Diet DP when I want a stronger flavor, and CZ for a smoother taste.
When I was a kid, I liked Orange and Grape Crush too, they really woke your mouth up
