stuff had Splenda in it. Aspartame and saccharine have the same effect.

I have an idea that the folks who make such drinks use way too much
sweetener. Certainly Diet Coke with Splenda was oversweet - and soon
disappeared from the shelves (where I live, anyway). I use Splenda
almost exclusively, and find that, used sparingly, I can't tell the
difference between it and sugar.

No doubt individual reactions will vary - but I can detect no adverse
effect from consuming Splenda.
