I still love a pepsi on ice, but I try really hard not to drink it anymore, and I've cut 99% of it out. And I've never really trusted (or liked the taste of) other sweeteners, so yes, it was the full sugar stuff. When you are younger and active, you can get away with drinking quantities like a normal reasonable human, maybe one or two a day, but now that I'm closing in on 60, I can't even do that anymore. So now, about the only exception I make is also for the odd rye & ginger.
I also know a guy who drank two 2-liters a day of mountain dew for much of his life, he's my age, I'm surprised he's still alive. He's so addicted to sugar that when we go backpacking for a week, he brings an entire bag of sugar and makes tea with it, and its gone by the end of the week. It's insane. But all that sugar is finally catching up to him.
Back in the day, you thought you were being healthy by giving your kids juice instead of pop, but its every bit as bad.
