Sugar, my ass.
They began using HFCS in the '80s & it's never tasted the same. I gave it up completely back then because I hated the taste of the damn corn syrup - yes, it tastes different from real sugar. I drank decaf iced tea instead and spent the calories I saved on pizza & Yukon Jack. It was a tasty trade-off that was made whenever I didn't have to drive anywhere...or do anything...or remain conscious.
