Pepsi Throwback.
I don't drink soda all that much, at least not the corn syrup stuff. I pretty much only use the throwback when in the mood for rum&coke at home. Probably amounts to three cases per year.
Same here. Regular soda, at least within a few hours of waking up for whatever reason, causes some.....intestinal issues.
I don't know if it's a placebo effect or what, though I'm not sure how my mind could cause these particular symptoms to manifest themselves; if my mind is capable of causing gas to show up out of nowhere, maybe it can spontaneously generate other kinds of matter as well. I doubt that though.
And I'm not much of a fan of the corn industry in its present form. Primary mission: Lobbying. Secondary objectives: Get subsidies, and maybe grow some corn.
Though if there was a similar product for Coca Cola, I'd might buy that. I've seen a variants of Coke that used sucrose as the sweetener. My dad bought it, and he didn't remember where.
Coke/Pepsi...they're different. But I don't know that I've got a preference.
