Back in the 60’s and very early 70’s, diet drinks used cyclamates as a sweetener, then it was banned.
Diet drinks actually tasted good then...................was used in Pre-Sweetened Kool-aid!.............No sugar needed!..............
I was very young, and remember a commercial featuring Davy Jones of The Monkees bragging that cyclamates had been removed from Kool Aid.
I could just about always taste an artificial sweetener, unmistakable and generally felt awful for a couple of hours.
